Thanks for the encouragement!
I made an appointment for tomorrow. I was so scared to call, and then it was no big deal. I just needed to wait a few days until the emotion of last week was more distant.
I will ask whether we can do anything to make sessions feel less critical. Maybe she will say that she doesn't think they are critical and ask why I feel that way; if so, I will try not to take it personally and storm off or close up!
Hearing from other people helped a lot. I will try to mention that tomorrow and see if she thinks some sort of group therapy would help. If I know I'm not the only person with issues like this, I feel like I'm not completely bizarre and helpless to change. Thanks again!
