Overthinking and anxiety

It ought to be simple. It is not even a big thing, really. But your thoughts have been running around it for hours now, testing every angle, imagining every possible outcome, and still there is no answer that feels certain enough.

Maybe it is a decision you cannot put down. Maybe it is a conversation from yesterday that you are still going through, sentence by sentence. Maybe it is the future in general, a vague sense that something ought to be solvable if you just think about it long enough.

It is one of the most exhausting forms anxiety takes, precisely because it looks like problem-solving. If you want to understand anxiety in a wider context, there is a fuller guide in anxiety: symptoms, causes and support. This article is about the specific version: when the thoughts will not stop, and what it is really about.

What the mind is trying to do

Overthinking is not a sign of being too sensitive or too weak. It is a sign of a mind trying to create certainty in a situation that feels uncertain.

The brain is built to predict and prepare. When something is experienced as threatening or unclear, a search switches on: is there an answer, a solution, a guarantee? That search is fundamentally helpful. The problem arrives when it is aimed at things with no single answer, at relationships, the future, other people's thoughts, questions of meaning, at everything that by definition contains uncertainty.

Then the thoughts circle without arriving. And the circling itself creates more worry, not less.

Why it feels productive while it is happening

Overthinking has a particular quality: it feels productive while it is going on. It feels like you are working at something, like you are about to reach the answer. But afterwards you are usually more tired and more worried than when you started.

Many describe it as a track in the head playing the same thing over and over. The thoughts move, but they circle rather than progress.

It can take more concrete forms too. Writing long mental lists of pros and cons for decisions that are not really that complicated. Analysing a short message from a friend for ten minutes. Lying awake going through tomorrow in detail, even though nothing unusual is planned.

You might recognise how the tiredness comes not from having done a lot, but from the thoughts never quite settling.

Why the thoughts will not stop

There is a psychological logic to overthinking that mirrors the one in avoidance. Instead of fleeing the discomfort, you try to think it away. To arrive at an answer that means the worry no longer needs to exist.

But uncertainty cannot be thought away. It can only be held.

In CBT rumination is described as a maintaining behaviour, a way of trying to control thoughts and feelings that in fact strengthens them. The more attention a thought receives, the more alive it becomes. That is not a logical flaw. It is how the brain naturally works.

ACT adds something important: the problem is rarely the content of the thought, but the fusion with it. When a thought feels like fact, like something you must respond to and resolve, it is hard to put down. But thoughts are thoughts. They are not reality, even when they feel very convincing.

You might recognise the difference between having a worry and being your worry. Overthinking blurs that line.

When it starts costing you sleep and decisions

Overthinking starts making a real difference to a life when it affects your ability to decide, to be present, or to rest.

Perhaps you notice that simple decisions take disproportionately long. That you put things off not because you are avoiding them, but because you do not feel ready, because you have not finished thinking. That you are physically in a conversation but mentally half elsewhere, because the thoughts are running in parallel.

Sleep is often affected early. The night is quiet and there are no outside impressions to point your attention at. The thoughts fill the space.

We often meet people who describe being tired of themselves. Not of life, but of their own thoughts. Who wish it were possible to switch off for a while. Who have tried arguing with the thoughts, distracting themselves, telling themselves to stop. And who have noticed that none of it really works in the longer run.

That is not a sign of weakness. It is a sign that something other than willpower is needed.

When worry is worth mentioning

It is common to think that overthinking is not serious enough to seek help for. That it is not real anxiety, just worry. That you ought to be able to handle it yourself.

But if the thoughts take energy you would rather spend on something else, if they affect how you sleep, how you decide, how you are with other people, that is reason enough to take it seriously.

Talking to someone is not about anything being urgent. It is about not carrying it alone, and getting help to understand what is actually going on.

What shifts in counselling

In counselling the shape of the overthinking gets explored concretely. Which subjects do the thoughts return to? What are they trying to solve? And what happens if they do not get an answer?

It is work that is often about changing your relationship to thoughts rather than removing them. Being able to notice that a spiral has started without automatically following it in. Finding a different way of holding uncertainty, one that does not require everything to be resolved before you can be in the present.

At ActWise Therapy we work with overthinking and anxiety in a calm, exploratory setting, focused on understanding and gradual change. You can read more about how we work with anxiety.

Change with overthinking is rarely about thinking differently. It is about needing to finish thinking a little less often.

It is fine not to have the answer yet

Maybe it is still turning a little after reading this. That is okay.

Understanding why thoughts behave the way they do does not change everything at once. But it gives you somewhere different to stand. A little more room. A little more distance.

That is enough for now.
