35 journal prompts for overthinking

Overthinking feels like thinking, but it goes round instead of forward. Writing it down breaks the circle: a loop on paper has a start, a middle and an end. These 35 prompts come from the journaling activities in the Mentis Overthinking plan.

By the Mentis wellness team · Updated 4 November 2026

In short
  • Write the loop down: what started it, what it said, how it stopped.
  • Next to every what-if, write what's actually likely.
  • Keep facts (what a camera would see) apart from the story your mind adds.

How to journal when you overthink

Psychologist James Pennebaker's research showed that writing about what's on your mind for 15–20 minutes, on a few days, can lift mood and even improve health over the following months (Pennebaker & Beall, 1986). For overthinkers, though, the kind of writing matters. Research on rumination finds that abstract "why" thinking keeps the loop spinning, while concrete "what happened, how, what next" thinking helps it settle (Watkins, 2008; Watkins et al., 2009). So these prompts ask for specifics: times, places, actual words, next steps.

Pick one prompt. Set a five-minute timer. Write without editing. Stop when the timer stops.

Catch the loop

  1. Pick one loop from the last day or two. What started it: a message, a thought, something you saw?
  2. What did it go round? Write the actual words it used, as near as you can get.
  3. How did it stop? Did something end it, or did it just run out?
  4. The three places or moments the loop most often starts for you: the bed, the bus, the family group, the quiet after dinner. One line each.
  5. The loops you caught today: what were they about, and what were you doing when each one started?
  6. When the loop runs, where do you feel it in your body: chest, jaw, stomach, hands?
  7. Everything your mind went round this week, one line each. Put each under "about something that happened" or "about something that might". Then count the sides.

Give it a time and a place

  1. What was on your worry list at your worry window today? Which still felt big when you got there, and which had gone small on their own?
  2. A day you did your loosening practice and a day you didn't. What was different about the evenings?
  3. This week, how many days did your body get properly keyed up, and how long did it take to settle each time?
  4. Finish this: "If I get three days in a row where my worry window doesn't happen, I ___."

Pair these with the worry timer.

From why to how

  1. Pick one thing your mind keeps going round. What exactly happened? Where were you, who was there, what was said?
  2. How did it unfold, moment by moment? What came first, then what, and what did you do?
  3. Now the next step: what exactly, when and where? If it's big, just its first ten minutes.
  4. The step you took this week: what happened after? Was it as big as the loop had made it?
  5. Rewrite your most common "why" question as a "how" question. "Why does this always happen to me?" becomes "How could I handle it next time?"

Check the what-ifs

  1. Each what-if that ran today, one line. Next to it, what's actually likely.
  2. The last time you checked (the message, the symptom, the question asked again), what did it give you, and for how long?
  3. The thing you did without checking: what did you predict, and what actually happened?
  4. Your what-ifs from last week: which came true, and which didn't? One line on what the count says.
  5. What's the worst realistic outcome, the best, and the most likely? Which one has your mind been treating as certain?

From "Today's What-Ifs", "Predicted, Happened" and "The Look Back" in the "What if, checked" chapter.

Fact or story?

  1. The conversation you keep replaying: on the left, only what a camera would have seen and heard. On the right, the story your mind added.
  2. A replay you closed this week: what was the fact, what was the story, and how long did the story keep going after you wrote it down?
  3. What would a neutral friend who was in the room say actually happened?

Good enough

  1. Every decision open right now, big or small. Next to each: what would be good enough?
  2. The decision you made this week against a "good enough" bar: did you reopen it? Was the regret the size you predicted?
  3. Where does "perfect" cost you the most time right now: work, messages, how you look, what people think?

Quiet the inner critic

  1. Today's critical sentence, and next to it what a friend would say. The friend's sentence has to be true.
  2. After the critic's sentence this week, what did you actually do? After the friend's sentence? Which one got you moving?
  3. Write to yourself about the thing you're hardest on, in the words a friend who knows everything about you would use. Five minutes.
  4. Whose voice does your inner critic sound like? Is it fair?

That second prompt has research behind it: people who were kind to themselves after a setback were more motivated to improve than those who were harsh (Breines & Chen, 2012).

Holding on to what works

  1. Which technique do you now reach for without thinking? Write it as "when ___, I ___".
  2. Finish this: "I'll know the overthinking is creeping back when ___."
  3. What's one loop that used to run every day and now rarely does? What changed?
  4. What would you tell someone who's where you were a month ago?

Frequently asked questions

Does journaling help with overthinking?

It can, as long as the writing goes somewhere. Writing that just replays the worry can keep it going. Writing that gets concrete (what happened, what's likely, what's the next step) is the kind linked with less rumination. The prompts here are built that way.

How long should I journal for?

Five to ten minutes is enough. In Pennebaker's expressive writing studies, people wrote for 15–20 minutes on a few days. Short and regular beats long and rare.

Should I journal at night if I overthink at night?

Better a few hours before bed. Late-night writing can stir the loop up. If thoughts keep you awake, try a short to-do list for tomorrow instead; one study found it helped people fall asleep faster.

What's the difference between rumination and reflection?

Reflection asks 'how' and moves towards a next step. Rumination asks 'why' over and over and stays stuck. If your writing keeps circling the same question, switch to a 'how' or 'what next' prompt.
