It' s okay if you don't like your T right now. When my T tries to help me keep from self-harming, I have mixed feelings about him. I love him for being so concerned and for validating the reasons as to why I do it but I hate him because he becomes the representation of the one who is trying to take away my freedom-- the freedom to do what I want to myself. Although it is ultimately my choice, it's hard not to see it like that sometimes.

It doesn't sound like you are slipping backwards. In fact, you seem to be moving forwards-- you are being honest with your T (yes, it was very good for you to tell him you didn't like him when you felt that way), and you are trying to keep yourself safe.

One rule for Ts is that a T should never work harder than than his/her patient. It sounds like your T is working pretty hard to help you-- so you must be working really, really freaking hard.
