I know how attached you are to your therapist and how difficult it is for you to think about leaving her; you've struggled a lot with it these past few months, and I'm so sorry she did what she did to you. But you are doing some really great work on your own right now! You are taking steps in a healthier direction, and it's all coming from YOU. That requires a lot of strength, and I'm sure it's rough, but it also sounds like a very empowering process. I'm so pleased for you!

About what AllHeart suggested: I get that you don't want to do something to make your therapist suspicious, but is there no way you could introduce the idea of cutting back to once a week without making her think it's for any other reason than just you wanting/needing to cut back?
