Writing Therapy Exercises: A Practical Guide
A writing prompt invites. A writing exercise structures. The difference matters. A prompt opens a door and trusts you to walk through. An exercise hands you a map, a protocol, and a reason to keep going when the writing gets uncomfortable.
The exercises below are not improvisations. Each one is drawn from a clinical tradition: expressive writing research, narrative therapy, gestalt practice, and cognitive restructuring. I have adapted them for self-use, but the bones are the same as the ones used in therapy rooms.
If you are new to writing therapy, start at the top and work down. The exercises build on each other. If you are returning, choose the one that meets you where you are.
1. The Pennebaker Expressive Writing Protocol
Developed by social psychologist James Pennebaker in the 1980s, this is the most researched writing intervention in the literature. The protocol is simple. The effects are not.
How to do it
- Write for twenty minutes a day, for four consecutive days.
- Choose one emotionally significant event or situation. The same one for all four days.
- Write your deepest thoughts and feelings about it. Not the facts. The feelings underneath the facts.
- Do not stop. Do not edit. Do not worry about grammar. If you run out of things to say, repeat the last sentence until something new arrives.
- When you finish, put the writing away. Do not re-read until day five.
Decades of research on this protocol show measurable improvements in immune function, sleep, working memory, and emotional regulation. Day one and two often feel worse before they feel better. That is the protocol working, not failing.
2. The Empty Chair Letter
Adapted from gestalt therapy. The original exercise asks you to speak to an empty chair as if someone you needed to address were sitting in it. The written version asks the same of the page.
How to do it
- Choose one person you have unfinished business with. Alive, dead, present, absent. It does not matter.
- Write them a letter. Begin with: "There is something I never told you."
- Say everything. Do not soften, do not perform fairness, do not edit for kindness. This letter will not be sent.
- When you are done, leave the page. Come back the next day and write a second letter, this time as if you were them, replying to you.
The exercise works because the second letter forces you to imagine the inner world of someone you have only experienced from the outside. That act of imagination changes what you carry, even when the person never knows you wrote it. It pairs well with the work in letting go of the past.
3. Narrative Restructuring
Drawn from narrative therapy, this exercise asks you to take a story you have been telling about yourself and write it twice. First as the inherited version. Then as the authored one.
How to do it
- Identify one sentence you say about yourself often. "I am not good with people." "I always sabotage things." "I am the responsible one."
- Write the story that this sentence belongs to. Where did it come from? Who first said something like it about you? What evidence keeps it alive?
- Now write the same period of your life, but this time foreground the moments that contradict the sentence. The exceptions. The other story that is also true.
- Finish with a new sentence that holds both versions: "I have learned to be careful with people, and I am still capable of closeness."
This is the core move of narrative therapy: separating the person from the problem, and then re-authoring the story with more of the truth in it.
4. The Unsent Letter
Older than therapy itself. The exercise is exactly what it sounds like: a letter you write with no intention of sending. It externalizes what has been circling inside.
How to do it
- Write to the person, place, or version of yourself you have been arguing with internally.
- Use their real name. Use the truth. The unsent letter is not a draft, it is its own form.
- When you finish, decide what to do with it. Some people burn it. Some keep it sealed. Some tear it up the next morning. The decision is part of the exercise.
5. The Worry Externalization
Adapted from cognitive behavioural writing tasks. Useful when anxiety has become a fog rather than a list. The exercise turns the fog into objects you can look at.
How to do it
- List every worry currently running in your mind. Big, small, rational, irrational. Do not filter.
- Sort the list into three columns: what is in my control, what is partly in my control, what is not in my control at all.
- For the first column, write one small action you can take this week. For the second, write one boundary or conversation. For the third, write one sentence of acknowledgement and release.
The exercise pairs well with journaling for anxiety.
6. The Future Self Letter
A letter from the version of you five years from now, written to the version of you reading this today. It works because it borrows the perspective you do not yet have, and gives the present a shape.
How to do it
- Picture yourself five years from now. Not idealised. Realistic, but slightly further along than you are now.
- Write a letter from that person to you. What do they want you to know? What do they wish you had stopped worrying about sooner? What did you do in the next twelve months that mattered most?
- Sign it with the date five years from today.
A note on doing the work alone
These exercises are powerful. That is the point. If something surfaces that feels too heavy to hold by yourself, please do not push through. Stop, ground, and consider working with a therapist alongside the writing.
Writing therapy is not a replacement for relational therapy. It is a companion to it. If you would like to write with guidance, you can book a private 1:1 writing therapy session with me.

Choose one exercise from this guide and commit to it for the next four days. Same time, same place, same notebook. Do not skip a day, and do not read what you wrote until the four days are over. On the fifth day, read it all in one sitting. Notice what surprises you.
Frequently Asked Questions
How long should each writing therapy exercise take?
Most structured exercises take between fifteen and twenty minutes per session. The Pennebaker protocol is classically four consecutive days of twenty minutes. What matters more than duration is uninterrupted attention. Set a timer and write without stopping.
Do I need a therapist to do these exercises?
No. These exercises are designed to be done alone with a notebook. They are drawn from clinical literature but adapted for self-use. That said, if an exercise surfaces material that feels too heavy to hold by yourself, working alongside a trained therapist is wise.
Which exercise should I start with?
Start with the Pennebaker expressive writing protocol. It is the most researched, the most adaptable, and the foundation that the other exercises build on. Once you have done four days of it, the empty chair letter and narrative restructuring will feel like natural next steps.
