Echoes, I use to write letters to my T almost weekly. We both knew I wrote them and that she received and read them but we didn't discuss them. I liked that she knew more than I could express yet talking to her. Eventually I went "cold turkey" and put a moratorium on writing her and insisted with myself that I talk to her in therapy sessions only. That was one of the biggest and best things I did for myself.

Were I you, I'd take the letter and read it to her. Letters, e-mails, books,(posts like this) etc. all get between us and the other person! I use to get comfort imagining my T reading my letters. But one of the operative words there is "imagining" -- we can imagine anything we want; that T's will be more or less helpful, will like or dislike us, that what we write them is too passive or that we're chickens :-) but we can NEVER know unless we ask them, talk to the other person, directly. I understand totally your fear/chickenness which is why I'm vicariously living through you and recommending you take the letter and read it aloud (hand it to her to read so you can see her face and discuss it then and there?); that's what I wish I had done sooner. Try to go for what will help you grow rather than what "feels" good/safe. I spent way too many years working on being "warm, dry, and safe" (my literal wants/goals).
