Okay, this is a great letter of course. Very honest and from the heart. I'm a little unclear - have you sent this already?

If not, before you do, I would have in my mind what kind of response that you want your therapist to provide to it.

What, exactly do you want to get out sending it? What would make it safer for you to continue with her versus not?

You do sound pretty confused and upset, what, in her response could help you to feel less so?

If you know, then I would likely include that in the letter. Specific points where she can help to move foreward.

Good luck.
