A calm, psychologist-written guide with gentle, ACT-based journal prompts for overthinking – to help you soften mental spirals, ease “what if” thoughts, and reconnect with what truly matters, one honest line at a time.
Overthinking is often described as “thinking too much”, but psychologically, it is much more than that. It is your mind working very hard to protect you from uncertainty, regret, rejection, or loss. When you care deeply, your brain tries to keep you safe by replaying conversations, analysing decisions from every angle, and predicting future outcomes. It’s understandable – and also exhausting.
Journaling offers a different way of relating to these thoughts. Instead of wrestling with them in your head, you gently move them onto paper. This slows your mind, gives structure to what feels chaotic, and helps you see the feelings and values that live underneath the noise. In Acceptance & Commitment Therapy (ACT), journaling is a practical way to build psychological flexibility: staying present, opening up to your inner experience, and moving in the direction of your values – even when your mind is busy.
You don’t need long, detailed entries or perfectly formed insights. A few honest sentences are enough to begin loosening the grip of overthinking.
When thoughts feel tangled, your journal becomes a soft place for them to land so you don’t have to carry them all in your head.
When your mind feels loud, journaling can become a steady place to land. When you are trapped in “what if?” loops, the page can help you sort through what you know, what you imagine, and what you truly care about. And when emotions build beneath the surface, your journal gives them a safe, private space to unfold at your own pace.
Tessa’s Tip: If you tend to overthink what to write, begin with one gentle line: “Right now, my mind is telling me…” You don’t need certainty before you write – clarity often begins to appear because you wrote.
Why journaling supports overthinking relief
From an evidence-based perspective, journaling supports overthinking relief because it engages several key processes at once:
- Cognitive processing – Writing slows your thinking and helps you make sense of fears, “what ifs”, and scenarios that feel overwhelming.
- Emotional labelling – Naming emotions (“I feel anxious”, “I notice shame”, “I feel uncertain”) reduces their physiological intensity and helps the brain calm down.
- Self-compassion activation – Kind, validating language soothes the brain’s threat system and reduces harsh self-criticism that often fuels overthinking.
- Values awareness – Journaling helps you reconnect with what truly matters beneath perfectionism, people-pleasing, and fear of making the wrong choice.
- Reduced rumination – Externalising thoughts onto paper interrupts looping mental patterns and keeps you from rehearsing the same worries again and again.
- Nervous system regulation – Slow, intentional writing cues the parasympathetic system (your “rest and digest” mode) and supports steadiness.
These effects don’t require long sessions or perfect structure. Even two or three minutes of honest writing can create a noticeable shift when your mind feels crowded.
How journaling supports the nervous system when you overthink
Overthinking doesn’t just live in the mind – it lives in the body too. You might notice a tight chest, a racing heart, a pit in your stomach, or a sense of restlessness that makes it hard to relax. Journaling can gently support your nervous system alongside your thoughts.
- It can move your system out of threat mode (fight, flight, or freeze) by slowing your pace and focusing your attention on one thing at a time.
- It builds interoceptive awareness – your ability to notice sensations (like tension, pressure, or warmth) without immediately judging or fearing them.
- It engages the parasympathetic nervous system: the part of your body that supports rest, digestion, and regulation, especially when paired with slow breathing.
- It lowers cognitive load by getting swirling, repetitive thoughts out of your head and onto the page, where they feel less urgent.
- It creates predictability; a small journaling ritual can become an anchor of safety when your mind tends to race at the same moments (for example, late at night or after social interactions).
When the nervous system feels even slightly safer, thoughts soften too. You don’t have to “deserve” calm – your body is allowed to exhale.
A practical ACT framework: the 6 processes behind effective overthinking journaling
In ACT, the goal isn’t to stop difficult thoughts, but to change your relationship with them. This is especially important when you overthink. The aim is not an empty mind, but a more flexible one: you can notice thoughts, make room for feelings, and still move towards what matters. Journaling can support all six core ACT processes:
- Present-moment awareness – Writing draws your attention out of autopilot and into this moment, instead of living entirely in the past or future.
- Cognitive defusion – Seeing your thoughts as words on a page helps you relate to them as thoughts (mental events), not absolute facts or instructions.
- Acceptance – Allowing your worries, fears, and “what ifs” to show up on the page reduces the struggle to push them away or control them.
- Self-as-context – Journaling strengthens the observing self: the calm part of you that can notice everything you think and feel without being defined by it.
- Values – Writing about what matters helps you see the caring intention behind your overthinking and rediscover direction, even when you feel stuck.
- Committed action – Journaling often naturally leads to a tiny, values-aligned next step you can take, instead of staying frozen in indecision.
Over time, this combination is powerful: you stop asking, “How do I get rid of these thoughts?” and start asking, “How can I live the life I want, even with these thoughts?”
A soft clinical insight
In my work as a psychologist, I’ve met so many people who quietly carry the weight of overthinking. They replay conversations, question decisions, and scan for anything they might have done wrong – not because they’re weak or dramatic, but because they’re trying so hard to be good, kind, careful, or successful.
Many tell me they feel embarrassed by how much they overthink. Some worry that journaling will make it worse, because they fear “getting stuck” on the page. What I often see instead is something deeply human: when unspoken thoughts finally find language, they soften. When fears are written down in full sentences, they feel less like endless fog and more like specific worries you can meet with compassion and perspective.
Emotional relief rarely begins with huge breakthroughs. It often starts with small, honest lines written tenderly, especially on days when your mind feels loud.
Common journaling mistakes for overthinkers (and gentler alternatives)
You’re not “bad at journaling”. If you tend to overthink, you’ve probably just been given rules that increase pressure instead of reducing it. Here are common patterns I see – with softer alternatives:
- Trying to “solve” every thought → Let your journal be a place to notice and explore, not a place that demands final answers.
- Using your journal as evidence that you’re failing → Shift from self-criticism (“Why am I like this?”) to curiosity (“It makes sense I feel this way, given what I’ve been carrying.”).
- Turning journaling into another perfectionistic task → Allow your entries to be short, messy, fragmented, or incomplete. Presence matters more than polish.
- Only writing during crises → It’s okay to use journaling on hard days, but including moments of calm, gratitude, or values can make it feel less like an emergency tool.
- Expecting journaling to make overthinking disappear → Let journaling hold your experience, not erase it. Over time, this holding changes how you relate to your thoughts.
- Comparing your journal to someone else’s → Your journal is for you. It doesn’t need to be aesthetic, shareable, or impressive.
Gentle rule of thumb: if your journaling increases pressure, it’s okay to rewrite the rules so it becomes a softer space.
How values make overthinking journaling more grounded (ACT perspective)
Without values, journaling about overthinking can turn into more rumination: you stay in the story of what went wrong or what might go wrong. With values, journaling becomes grounding. It reminds you why your mind is so active in the first place – because something deeply matters.
Values are the qualities you want to bring into your life: kindness, honesty, steadiness, courage, creativity, presence, connection. When you write from a values lens, your journal shifts from “What is wrong with me?” to “What is important to me, even here?”
You might try asking:
- “What does my overthinking reveal about what I care about?”
- “If fear wasn’t deciding for me, what value would I want to move towards?”
- “What would the ‘me I want to be’ choose as a small, kind step right now?”
Tessa’s Tip: If you feel stuck in “What if?” thinking, pick one value (for example: compassion, courage, honesty, boundaries) and begin your entry with: “Today, I want to move 1% closer to…” Let the sentence gently unfold from there.

Mini FAQ about journaling for overthinking
How often should I journal if I overthink a lot?
As often as it genuinely supports you – not as often as you think you “should”. Some people find a short daily check-in helpful, others journal a few times per week, and some only on particularly busy-mind days. Even one honest paragraph can be meaningful. The goal is relief and clarity, not perfect consistency.
What if journaling makes me spiral more?
It’s common to feel like writing might make worries bigger at first, because you’re finally turning towards what you’ve been avoiding. To reduce spiralling, use gentle structure (like the 4-step flow above), write for a set time (2–10 minutes), and end with a values-based or self-compassionate line. If your anxiety or overthinking feels overwhelming or unmanageable, consider reaching out to a mental health professional for additional support.
What if my journaling is messy or short?
Messy is human; short is enough. Overthinking often pushes you toward perfectionism, but your journal does not need to be neat, aesthetic, or profound. Its purpose is to hold your experience in a kind way. A few truthful lines can be more healing than a carefully crafted page written from pressure.
Can journaling really help with overthinking?
Journaling won’t remove every worrying thought from your life, but it can change the way you relate to them. By writing, you slow down, name your emotions, reconnect with your values, and create a sense of distance from your thoughts. Many people find that their mental spirals become less intense and shorter over time when they regularly combine journaling with gentle self-compassion.
Tessa’s Tip: Gentleness is not the opposite of change – it’s the foundation of sustainable change. Your overthinking doesn’t need more pressure. It needs more understanding.
Gentle reflections to carry with you
- Your overthinking is not proof that something is wrong with you – it’s proof that something matters to you.
- Your journal doesn’t need perfect answers; it simply needs your honest presence.
- Thoughts often soften when they have somewhere safe to go.
- Values can act as a quiet compass when your mind feels busy, loud, or confused.
- Two minutes of sincere writing can gently change the emotional direction of your day.
Closing
Journaling for overthinking is not about forcing your mind to be quiet. It’s about creating an inner space where thoughts can land, emotions can be felt, and your values can speak a little louder than fear. With time, small, consistent moments of writing can transform the way you relate to your busy mind – not by erasing it, but by meeting it with more clarity and compassion.
