How to Stop Overthinking
By Mahsa Hamedanizadeh, MCP, RCC · October 20, 2026
Why your mind keeps replaying and rehearsing, and what actually helps it slow down
You go to bed tired, and then your mind starts. A conversation from this afternoon replays. A message you sent gets reread in your head. Tomorrow’s meeting runs through every way it could go wrong. Overthinking is one of the most common reasons people reach out for counselling, and one of the most exhausting things to live with.
The good news is that overthinking is not a character flaw. It is a pattern, and patterns can change.
What overthinking really is
Overthinking usually takes one of two shapes:
-
Replaying: going over what already happened, looking for what you did wrong or what someone really meant.
-
Rehearsing: running through what might happen, trying to prepare for every possible outcome.
Both feel like problem solving. Your mind is trying to keep you safe by finding the mistake before it costs you, or by preparing for the worst so it can’t surprise you. The trouble is that real problem solving ends in a decision. Overthinking just loops.
Why it is so hard to stop
Telling yourself to “just stop thinking about it” rarely works, and there are good reasons for that.
-
Anxiety keeps the loop running. When your body feels on edge, your mind looks for a reason. It will find one.
-
It feels responsible. Many overthinkers learned early that being careful, prepared and alert kept things calm. Letting go of the worry can feel careless, even dangerous.
-
Uncertainty is uncomfortable. Overthinking promises that if you think hard enough, you will finally feel sure. That certainty rarely arrives.
Small things that help
These won’t end overthinking overnight, but they can loosen its grip.
-
Name it. Saying “I’m replaying again” or “this is rehearsing” puts a little distance between you and the thought. You are noticing the loop instead of living inside it.
-
Ask one useful question. Is there something I can do about this today? If yes, choose one small step and do it. If no, the thinking is not helping, however urgent it feels.
-
Give worry a time slot. Set aside fifteen minutes in the early evening to write down everything on your mind. When a worry shows up at midnight, remind yourself it has a time tomorrow.
-
Come back to your body. Overthinking lives in the head. Slow breathing with a longer out-breath, feeling your feet on the floor, or a short walk can tell your nervous system that right now, you are safe.
-
Notice the themes. Over a week, what does your mind keep returning to? Rejection, failure, being a burden, getting it wrong? The theme often says more than the details.
When it is time to talk to someone
Self-help tools are a good start. It may be time for more support if:
-
Overthinking is affecting your sleep, work or relationships.
-
You feel anxious or on edge most days.
-
The same worries have followed you for years.
-
You have tried to manage it alone and feel worn out.
In counselling, the aim is not only to quiet the thoughts but to understand them: where the pattern began, what it has been protecting you from, and what you need now instead. When the underlying anxiety settles, the mind usually stops working so hard.
