How to stop overthinking (without trying to stop thinking)
The same thought keeps coming back. You go over it again in the shower, at your desk, at 2 a.m. It feels like you're working on the problem, but nothing gets solved. Here's why that happens and what helps.
Is this worry useful? A quick test
Robert Leahy, one of the leading experts on anxiety, doesn't say "stop worrying." In The Worry Cure he suggests worrying more effectively. Productive worry follows three rules: the problem is plausible, you can do something about it now or very soon, and you move quickly from "what if" to a step.
Unproductive worry is a chain of what-ifs, each hanging on the one before, none leading to action. So ask: "What can I do about this today?" If the honest answer is "nothing," it's not a task. It's worry, and it needs a different approach.
Why overthinking feels like it's helping
Leahy describes a paradox: while you're worrying, you actually feel a bit less anxious. Worry is words and reasoning in your head, and it screens out strong feelings and frightening images. That's why it feels like useful work. But the anxiety doesn't go away; it keeps simmering underneath.
The same goes for asking for reassurance: checking with friends again, rereading, searching. It brings a few minutes of relief, and then the doubt returns. Leahy compares it to checking a lock: check the door forty times and next time you'll check it forty-one.

One of Leahy's best-known tools is worry time: a set 20 to 30 minutes, say early evening at a desk, when you write your worries down without arguing with them. If a worry pops up during the day, jot it on a note and save it for later.
After a couple of weeks two things usually become clear: worry can be postponed, and it repeats itself. As he puts it, it's not ten million worries, it's ten. Many people even get bored during worry time, which is a very good sign.
Thoughts are not facts
The authors of The Mindful Way Through Depression describe thoughts as events in the mind that may or may not reflect reality. Seen as a thought, "this will never get better" loses some of its power. Arguing with such thoughts when you're low often makes them louder; noticing them ("there's that thought again") works better.
Russ Harris, in The Happiness Trap, adds a useful image: a "struggle switch." When it's on, any unpleasant feeling becomes unacceptable, and new ones pile on top: anxiety about your anxiety, frustration that you can't stop thinking. Switching it off doesn't make the feeling pleasant, but it stops the pile-up.
A small first step
- Write down the thought that keeps returning.
- Ask: can I do something about it today? If yes, write the smallest step and do it. If no, put it on tomorrow's worry-time list.
- Notice one reassurance check you'd normally do, and skip it once.
When to get more help
If worry fills most of your day for weeks, comes with panic attacks, or stops you from working, sleeping, or going places, it's worth seeing a doctor or therapist: anxiety responds well to treatment.

Is overthinking a sign of anxiety?
Often, yes. Repetitive worry is one of the most common faces of anxiety, though it can also show up with low mood or stress.
Why do I overthink at night?
During the day you're busy, and at night the head finally has quiet. Writing worries down earlier in the evening, with a next step for each, often helps.
Can I just distract myself?
Short distraction is fine, but if you use it to avoid the feeling every time, the worry tends to come back. Worry time and noticing thoughts work better over weeks.
