Why Your Therapist Might Suggest Writing a Letter (Even If You Never Send It)

Therapy doesn’t usually come with homework, but every now and then your therapist might suggest something unexpected—like writing a letter. Not necessarily one you’ll ever send, but one that helps you put your thoughts and feelings into words. At first it might feel a little awkward, but letter writing is a surprisingly powerful tool for processing emotions, finding clarity, and even practicing the things that feel hardest to express out loud.

So why letters? Therapists don’t hand out assignments just for fun. Letters work in ways that verbal conversation sometimes can’t.

1. Letters create space for clarity.

When feelings are tangled, writing helps untangle them. Putting thoughts into words forces us to slow down enough to notice what we’re actually feeling (not just what we blurt out in the heat of the moment). A letter can turn the overwhelming mess in your head into something concrete you can see and make sense of.

2. Letters allow you to say what can’t be said out loud.

Sometimes we need to express things that feel too scary, vulnerable, or risky to say face-to-face. A letter—especially one you may never send—becomes a safe container for honesty. You can rage, grieve, thank, or question without worrying about anyone’s reaction in real time.

3. Letters can bridge past, present, and future.

Therapists might encourage writing to your younger self, your future self, or even to the version of you that exists right now. This isn’t just poetic—it helps build self-compassion, perspective, and insight. Think of it as a way of stitching together different parts of your story.

4. Letters are rehearsals.

Sometimes, you do want to say something important to someone. Writing it down first helps you figure out what matters most, what tone you want to use, and how to express it with clarity rather than reactivity. Even if you change your mind about sending it, you’ll have practiced finding your voice.

5. Letters create a record of growth.

Going back and rereading what you once wrote can be powerful. You may notice healing, shifts in perspective, or how much more grounded you’ve become. It’s like leaving breadcrumbs for your future self.

A quick therapist’s note

Remember: not every letter needs to be shared or mailed. In fact, most therapeutic letters stay right where they were written—between you, your notebook, and sometimes your therapist. The power often lies in the writing itself, not in the delivery.

And if your therapist suggests writing a letter, it’s not because they’re grading your penmanship. It’s because they know you deserve a space to say things your voice might not be ready to carry yet.

👉 Whether or not you ever put a stamp on it, letter writing in therapy is less about the recipient and more about you. It’s a tool to help you clarify, process, and heal—and your therapist is there to guide you through it.
