Many therapists would welcome your honesty and your thoughts about the relationship dynamic. Any good therapist will listen and respond kindly to you opening up about your feelings. I felt a lot better after disclosing my feelings, I did it gradually, at my own pace. It's not a walk in the park, but it helps to be open. You said that you are worried about her transferring you? I think fear of abandonment (or feeling being too much for the T to bare) is very common in these situations - so when you tell her and she stays with you, that's going to be a big part of the healing process for you. Good luck!
