Uncertainty Disguised as Anxiety: A Psychotherapist's Personal Reflection

If you have ever lain awake at three in the morning, your mind running the same loop over and over, searching for an answer that that never comes, you already know that understanding anxiety is not the same as being free of it.

I know it too.

I learned about anxiety through lived experience, then books, and later through a lesson that no book quite prepared me for.

One that came from turning inward, and stumbling upon something I had somehow failed to grasp for most of my adult life.

Something that, once seen, reframed not just my understanding of anxiety, but the story of my own life.

I come to it from two directions:

As a psychotherapist who has spent years studying the clinical landscape of fear and worry, and as an individual who has, throughout a large portion of my life, been entirely consumed by both.

For a long time, the books gave me language.

The scientific literature gave me understanding.

My clinical training gave me tools I could pass on to others.

And yet, even with all of that, something remained unresolved.

A question that neither the books nor the clinical model ever quite answered

It was only when I turned inward, when I stopped reading about anxiety and started genuinely examining my own experiences of and relationship with it, that the picture began to clarify.

What I found was not what I expected.

This essay is my honest attempt to paint that picture for you.

To put into words an experiential insight that needs to be fully felt to be fully understood.

At the end of it, I share what that realisation was, how it shaped the way I moved through the world, and the way I showed up, or failed to show up, in my own life. Along with what it eventually taught me.

I think it may resonate with more people than I initially expected.

Anxiety vs Uncertainty: Why the Difference Matters

We often describe anxiety as a fear of what is coming. Something bad is going to happen.

As if the outcome is already certain.

That is a common understanding, and it is not wrong, but I think it is incomplete in a way that matters enormously.

Consider the difference between these two experiences.

In the first, you are anticipating something difficult that you are almost, if not completely certain, is going to happen.

You may even believe you know when and how it is going to happen.

A painful conversation, a loss, a failure you can already see taking shape.

That knowledge is hard to carry. It can even be devastating.

But it has a shape.

And a known shape, however painful, is something the mind and body can begin to organise around.

It has a timeline, a known difficulty, a beginning and an end you can prepare for.

You can grieve it, steady yourself against it, call on every previous version of yourself that faced something similarly terrible and survived, and draw some quiet confidence from that fact.

In the second experience, you are also anticipating something difficult.

But the sense of certainty is non-existent.

You do not know if it will or won't happen.

If it does happen, you do not know when, how bad it will be, or whether you will be able to bear it.

Think of someone awaiting a hip operation versus someone who has just been told they may have cancer, with ten days to wait for results; no diagnosis, no prognosis, and no idea what any of it means for the life they thought they were living, and the future they desired to live.

Both are in the grip of anticipatory anxiety.

But for the second person, the depth and weight of uncertainty, in all its forms, can become an additional source of suffering, often surpassing the feared outcome itself.

You suspect.

You fear.

You swing back and forth.

One moment the dread is absolute; the next, a small light of hope appears and you think perhaps you were wrong, maybe it will be fine.

Then the light goes out again.

And you are back in the loop, your mind turning the same unanswered questions over and over, searching for a resolution that refuses to come.

And what makes that so exhausting is not just the fear itself but the not knowing.

The ifs.

The whens.

The endless mind-made scenarios.

The brain, in its deep need for resolution, keeps running the same calculations, hoping that this time it will arrive at a definitive answer.

It rarely does.

Because the nature of the future is that it cannot be known, no matter how hard we try to force it into certainty.

Which is why I believe that for many of us, the real struggle is not with anxiety itself. It is with the uncertainty that quietly drives it.

What Most People Get Wrong About Anxiety

During my psychotherapy training, one of the requirements was to undergo personal therapy.

My therapist shared a perspective on anxiety that I have carried with me ever since.

She described it as this:

Something bad is going to happen, and I do not have the ability to cope with it.

It is a precise and interesting definition.

But sitting with it over the years, I have come to feel that it describes something slightly different from what I have experienced myself.

There is, subtly embedded within it, a quiet certainty, albeit cognitively distorted:

The bad thing will happen. I will not cope.

The outcome is written, even if it is written badly.

My own experience has always felt more like this:

I have a sense that something bad might happen, I don't know when, where and how, and I am not sure that I will be able to cope with it if it does.

That small shift, from certainty to suspicion, from will to might, changes everything.

It is not just the anticipated, dreaded outcome that generates the suffering.

It is the not knowing whether that outcome is coming at all, and if it does, when that day might be.

The Open Loop: Why Your Brain Cannot Switch Off Anxious Thoughts

There is a useful way to think about what uncertainty does to the mind.

Put simply, it creates an open loop.

The brain, which is fundamentally a pattern-seeking, resolution-seeking organ, encounters a question it cannot answer.

And so it keeps working.

It cycles through the same thoughts, revisits the same fears, builds and dismantles the same scenarios, because it is trying to find the answer that will allow it to finally rest.

What the Amygdala Does During Anxiety

When we are persistently anxious, the brain's threat detection system, centred around the amygdala, becomes highly activated.

In this state, the part of the brain responsible for clear thinking and problem solving, the cortex, becomes less accessible.

We are not stupid or irrational when we are anxious.

Instead, we are operating from a system that was designed for immediate survival, and to prevent us from wasting essential time thinking about what the best move might be when faced with immediate threat.

A system that can override our ability for clear, rational, and effective thinking.

And in that state, the loop does not slow down.

It accelerates.

The problem is that most of the things we are anxious about are external.

They involve other people, future events, outcomes we cannot predict or control.

The answer the brain is searching for exists, if it exists at all, somewhere outside of us.

And that means it is not reliably or immediately available.

We cannot always obtain it, no matter how long we spend looking.

Yet the brain keeps looking.

This, I believe, is why so much of conventional anxiety management falls short for so many people.

It addresses the content of the worry without addressing its roots and structure.

It tries to help you think differently about the thing you are afraid of, when what is actually needed is something more fundamental:

A way to close or interrupt the loop when the external world or your mind refuses to do it for you, by working at a level deeper than thought.

Does Anxiety Start in the Mind or the Body?

Here is something that took me a long time to truly understand, and that I think is worth saying as directly as possible.

We tend to assume that anxiety begins in the mind.

That a thought arises, a worry takes hold, and the body follows.

The racing heart, the shallow breath, the tight chest, the restlessness, all of it feels like a consequence of thinking too much.

In the field of biology and psychology, this is known as a "top down" approach.

But in my experience, both personal and clinical, this perspective oversimplifies a complicated process which is actually bidirectional.

The mind and the mood are not always the origin of anxiety.

More often than we realise, they are the echoes of its origin.

What generates the experience, what sets the whole thing in motion, frequently begins in the nervous system.

In other words, it starts from the bottom up.

The brain and body register threat. The mind then scrambles to explain why.

This matters, because it means that thinking your way out of anxiety has a ceiling.

You can reframe a thought, challenge a belief, reason yourself into a calmer perspective, and still feel the anxiety humming beneath all of it, because the nervous system has not received the message.

The body is still braced.

Still waiting.

Still scanning for threat.

This is not to say that our thoughts don't matter; cognitive interventions are a vital part of the puzzle.

But if we only address the mind, we are only addressing half of the conversation.

To genuinely move through anxiety rather than simply manage it, you have to also work at the level where it actually lives.

Not in the thoughts, but in the body.

Not in the story the mind tells, but in the nervous system that generates that story.

How to Calm Your Nervous System When You're Anxious

Over time, I have found two practices that do this for me more reliably than anything else.

I share them not as prescriptions but as personal anchors, offered in the spirit of honesty that I hope runs through this whole piece.

Breathwork for Anxiety

The first is breathwork.

The breath is one of the very few physiological processes that is both automatic and within our conscious control, which makes it an effective tool.

When the nervous system is dysregulated, the breath tends to become shallow and fast, feeding the very state that produced it.

Slowing it down deliberately, particularly extending the exhale, can signal to the nervous system that it is safe to soften.

And when the nervous system gets that message, it sends a corresponding one to the brain.

The mind and mood, in turn, then tend to echo this message of safety.

I have found this to be one of the most immediate and accessible ways to interrupt the loop.

Not by solving the uncertainty, but by changing the physiological conditions in which the brain is trying to process it.

Why Exercise Helps With Anxiety

The second is body-based movement.

Exercise, for me, is not primarily about fitness. It is about discharge.

Anxiety is, at its root, a mobilisation response.

The body prepares itself for action, to fight off or flee from a perceived threat.

Stress hormones flood the body, breathing quickly to pump oxygen around it, mobilising and tensing its muscles, sharpening its senses.

When no action follows, all of that energy has nowhere to go.

It stays in the system, cycling.

Movement can give it somewhere to go.

It completes the loop that the threat response opened.

And in doing so, it allows the nervous system to return to something closer to rest.

Neither of these practices removes uncertainty from the world.

They do not answer the unanswered questions.

What they do is change the state from which you are facing those questions.

And that, in my experience, is powerful.

Your own anchor might look entirely different.

Stillness, cold exposure, time in nature, movement of any kind.

The specific practice matters far less than what it does to your nervous system.

The mechanism matters more than the method.

How to Build Self-Trust When You're Anxious

If the loop cannot be closed from outside, and the mind alone cannot close it, then the resolution must begin with the nervous system.

Because the nervous system must first reach a state of relative safety before the mind can genuinely receive what comes next.

And what comes next is not a prediction.

It is not a promise that things will turn out well.

It is something far simpler, and far more durable than either of those things.

It is the quiet, grounded, intuitive knowledge:

I will be okay.

Not told to ourselves as an affirmation, but felt in the body as a truth.

Research suggests that for many people, positive self-statements (affirmations) can widen the gap between what you are saying and what you are actually feeling, particularly when the nervous system does not yet believe it.

In other words, they can backfire.

Reassurance has to be felt before it is affirmed.

And the nervous system has to be part of generating it.

Notice what that statement does not say.

It does not say the difficult thing will not happen. It does not promise a particular outcome, or ask the future to behave in a way that suits you.

It says only that whatever comes, you will be able to meet it.

That is a very different kind of reassurance from the one anxiety craves.

Anxiety wants to know what will happen, when and how.

This asks instead:

Who and how will you be if and when it does?

The goal, then, is not to develop certainty about the external world.

That is neither realistic nor ultimately possible.

The goal is to develop genuine trust in yourself.

In your own resilience.

In your capacity to endure difficulty, to grieve what needs to be grieved, to adapt, to continue, and ultimately, to come out the other side.

This sounds simple, but is by no means easy.

Regulation creates the conditions for that trust to be felt. Evidence, accumulated over time through the moments where you showed up for yourself and survived, builds it into something lasting.

That kind of trust does not come from wishful thinking.

It comes from the slow, patient work of demonstrating to yourself, again and again, that you can be relied upon.

Which we will explore in the next section.

How Small Daily Actions Build Resilience Against Anxiety

We build trust in people by watching them show up, again and again, across different circumstances and different seasons of life.

That consistency creates a sense of predictability.

Of safety.

We build trust in ourselves the same way.

Through the accumulation of moments where we faced something hard and did not fall apart.

Where we kept a promise to ourselves.

Where we chose, in some small way, to honour who we are and what we value, even when it would have been easier not to.

Each of those moments is a deposit.

Over time, they become a foundation.

The specific practice will be different for everyone.

What matters is the principle:

Find something that belongs entirely to you, that you can choose and act on regardless of what the external world is doing, and do it.

And if this one thing can simultaneously regulate your nervous system, like breathwork, exercise or cold exposure, even better.

Not to distract yourself from anxiety, but to quietly remind yourself of your own agency.

To build, one small act at a time, a strong and growing case for your own capability.

An honest admission

I want to end with something I think is important to say plainly.

I do not have this fully resolved.

I am writing this not from the vantage point of someone who has "arrived", because I believe nobody ever truly does, but from the middle of an interesting journey that I suspect will continue for a long time yet.

Only recently have I begun to see clearly that for most of my life, I was living in a state of profound uncertainty.

Not just about specific events or outcomes, but about something more foundational.

A kind of groundlessness.

A lack of a solid and trusted self or base beneath everything else.

And how, over time, that conditioned my nervous system to continually keep a watchful eye on the world, braced for whatever might be coming.

It shaped more than just my inner life.

It shaped how I showed up in the world, in relationships, in the choices I made, both helpful and unhelpful, and the ones I quietly avoided.

I learned, without ever consciously deciding to or realising, to always have an escape plan.

To never fully arrive anywhere, in case I was forced to leave.

To keep one foot out, just in case.

Not out of indifference, but out of a deep, unexamined fear of being caught off guard. Of being hurt and being unable to bear the brunt of it.

This was not a weakness, but a necessary adaptation to the environment I grew up in.

One that stayed long after the environment that created it was gone.

And that realisation was by no means comfortable.

But it was clarifying, and quite liberating.

Because if the absence of that internal ground is what has been generating the anxiety, then the work is at least pointed in the right direction.

Not outward, toward a world that will never be fully knowable or controllable.

But inward, toward a self that can be trusted, cultivated, and returned to.

Knowing this and fully living it are not the same thing. But knowing it is where the work begins.

Anxiety, in the end, is a question.

An oftentimes relentless, circular, exhausting question:

Will I be okay?

The answer cannot be found in the future, because the future does not yet exist.

You may not even find it in the present.

However, one thing I am confident of is this:

The closest we can get to the answer is through the slow and patient work of becoming someone who develops the type of intuitive trust which affirms, with genuine conviction:

Yes. Whatever comes, I know that I will be okay.
