Im so glad you gave her the letter- I do the same (i.e cant bring myself to read it to T so get him to read it in his head - NOT OUT LOUD-NO WAY- could not handle that !!!).

I hate it when they come out with oh, its the transference...you're projecting...etc. No, these are my REAL feelings, why can't you see that ???!!! But it sounds as though she really does care about you. I think that now she knows about some of the feelings you have been hiding, it will help her to help you. You might have written things in the letter that she was unaware of, and it can help her to adjust her approach and to be more sensitive to you.

Well done for having the courage to let her know
