I think this is a great idea! Writing has allowed me to tell T so many things I wasn't ready to speak yet.
There have been times we've written an entire session, back and forth, and times when I've written and he's talked.
Now, I will usually start writing and then once the story starts being told in writing, I can open my mouth and say it. Or I will tell the story but write the hard parts.
And I like that you are going to talk about why it's scary to talk. I've had to do A LOT of that in therapy, and it helps.
