she gasped a very sharp intake of breath and recoiled back before she caught herself doing it.
I'm disgusted by this therapist. I don't care what you said. You were obviously ashamed and repentant. It's not like you were sitting there bragging about it.it was just words, her whole presentation of them was that she didn't believe in anything she was saying.
I guess it is preaching to the choir to tell you that this is not how therapists are supposed to be. Withholding personal judgement is a bare minimum requirement to practice -- if they can't take the heat, they should get out of the kitchen.
That said, I think it is probably a good idea to stay the course with your therapy, since you have no other options. Perhaps she has realized that her behavior was wrong and will show a change in the next session.
Since you can't lie down, I guess you could avert your eyes from her or even close your eyes as you talk. Try not to focus on her reaction.
