Your therapist is really rude. She can feel however she feels, but to face palm in session is beyond disrespectful. I wonder if confronting your T about how obnoxious she is may actually be therapeutic for you, since you are so uncomfortable with the idea. Therapy is a great place to practice this kind of stuff. Otherwise, maybe you should consider taking some time off from therapy. If the idea of not going makes you happy, then maybe you should follow your instincts.
