Meeting a new CBT specialist today.

I got back from residential yesterday, and feeling quite anxious about everything. This t will be the one replacing the one I had before and that makes me extremely angry. I am trying to go into this with an open mind but I really feel like just ranting. I want to make a good first impression but this is the t that is the reason I can't see my old t. I am confused and angry and upset and I really just want this initial meeting to not be a disaster.
