You can't switch worry off, but you can change what you do with it. Sort each worry by one question (can I act on this now, later, or not at all?), give the "later" ones a set time, and practice letting the rest pass. This guide covers a sort-it step with a worked example, a short postpone-and-note routine, a few ways to let the rest pass, and a plain section on what the NIMH and the NHS say about worry that is hard to control.
It is about "what if" thoughts: things that have not happened and may never happen. If your mind replays the past or loops on the present, or you want to tell useful problem-solving apart from rumination, our guide to how to stop overthinking is a closer fit.
Step 1: Sort the worry (now, later, or not at all)
Worry is not a flaw. The aim here is to keep the useful part (spotting something to prepare for) and drop the loop. Sorting is how you separate the two.
Take a minute and write the worry as one plain sentence. Then ask one question: can I act on this?
| Answer | What it means | What to do |
|---|---|---|
| Now | There is a small step I can take in the next hour | Do the step, or start it for five minutes |
| Later | There is a step, but it belongs at another time or needs more information | Put it in your calendar or list with a day and time |
| Not at all | It is out of my hands, or only a "what if" with no step to take | Name it, let it go for now, and return to what is in front of you |
A worked example
Say you have a medical check-up next week and your mind keeps jumping ahead.
- "What if they find something?" There is no step for this today. That is not at all: note it and let it pass.
- "I never booked a ride there." That is now: book it.
- "I should write down my questions for the doctor." That is later: add it to Thursday evening.
Three worries became one action, one appointment with yourself, and one thought you practice letting go of. You may find the pile feels lighter once each item has a label, though that is a hope, not a promise.
Common mistakes when sorting
- Calling everything "not at all." Be honest. Many worries hide a small step.
- Doing the step in your head. "I'll sort it out" is not a step. Write the actual action.
- Sorting at midnight. Late at night, everything feels bigger. If it is bedtime, write two words and follow the steps in our guide for racing thoughts at night.
Step 2: Park it with a postpone-and-note routine
Some worries do not fit any box today. They keep knocking. Worry postponement means you decide on a time later to worry about it, and until then you note it and move on.
This differs from the worry-time sections in our guides on overthinking and racing thoughts at night: here the slot exists only to run the now/later/not-at-all sort from Step 1, not to think things through.
A randomized waitlist-controlled trial, "Worry Postponement From the Metacognitive Perspective," tested postponement. Participants were told to postpone their worry to a predetermined later time. The authors say worry postponement with a stimulus control rationale appears effective in non-clinical samples, but that preliminary research in people with generalized anxiety disorder did not support its efficacy. In their own trial, the GAD group had lower worry scores than the waitlist group. The paper also reports that effects persisted to a four-week follow-up. Read that result with caution: it is one trial, and it sits next to preliminary research in people with GAD that did not support its efficacy. Treat postponement as a tool to try, not a promise.
The setup below is our own practical suggestion, not the trial's protocol, so adjust it to your day:
- Pick a worry slot. We suggest a short slot, around ten to fifteen minutes, at the same time each day and well before bed.
- Keep a "parking" note. A paper pad or notes app. When a worry shows up, write a few words and the time.
- Say a short line. "Noted. I will think about this at 5:30." Then go back to what you were doing.
- At the slot, read the list. Sort each item with the now/later/not-at-all question. Some may feel smaller by then. If one still has a step, give it a day and time.
- End on time. When the slot ends, close the note. If new worries come, add them to tomorrow's list.
Expect the first days to feel odd. The thought will come back, and that is not failure. Each time you note it and return to your task, you are practicing.
Step 3: Let the rest pass
The "not at all" pile needs a different skill. You are not arguing with the thought or proving it wrong. You are noticing it and choosing where to put your attention.
These steps are practical suggestions from this guide, not advice from NIMH, the NHS or the trial:
- Name it. "That's a worry about next week."
- Slow your exhale for three or four breaths. Our breathing exercise page has a simple pattern.
- Come back to the senses. Feel your feet, and name three things you can see. The grounding techniques guide lists more.
- Practice letting go on a quiet day, when the stakes are low. See letting go for five steps.
If the worry comes with a tight body and a racing heart, our meditation for anxiety guide may be a better place to start.
Where the app can help
AI Meditation: Sleep & Calm can give you a calm moment to practice the "let it pass" step. After a short mood check-in, the app writes a new meditation for that moment, read aloud by a synthetic (AI) voice. You can also use the practice mode with a timer. The parking note and your calendar stay your tools for sorting; the app is one optional moment of practice in between. You can try it for free, no account needed.
When worry is more than everyday worry
The sources draw the line not at worry itself but at worry that is hard to control and gets in the way of daily life.
NIMH describes generalized anxiety disorder (GAD) as including excessive worry about everyday things and trouble controlling worries or feelings of nervousness. It says that to be diagnosed, a person must find it difficult to control worry on most days for at least 6 months. NIMH also lists trouble falling or staying asleep and fatigue among the signs.
The NHS describes it as feelings of stress or worry that affect your daily life and are difficult to control. It advises seeing a GP if you think you might have GAD, and also if you have been diagnosed and treatments are not helping.
Note the difference between the two: the 6 months comes from NIMH and is part of how a diagnosis is made. The NHS describes GAD by how worry affects daily life and how hard it is to control, and it ties its GP advice to whether you think you might have GAD or whether treatments are helping after a diagnosis.
Putting the NHS points into a quick check:
- You think you might have GAD: the NHS says to see a GP.
- You have been diagnosed with GAD and treatments are not helping: the NHS says to see a GP about that too.
- Neither fits, and you want a better way to handle everyday "what ifs": this is where the steps in this guide come in. That is our suggestion, not a medical rule, and if you are unsure which line applies to you, ask a doctor.
Your health
This guide is general wellbeing information, not medical advice, and the app does not diagnose or treat anything. The NHS describes generalized anxiety disorder as worry that affects daily life and is difficult to control, and it advises seeing a GP if you think you might have it. It gives the same advice if you have been diagnosed and treatments are not helping. The NHS page on generalized anxiety disorder has more.
