I know you feel horrible and I wish you weren't feeling so bad, but I believe that it's progress. You have to go through all the yucky feelings in order to get better. Talking to your T is going to help; it just takes time (a quote from my T). Can you do some artwork or distract yourself so you don't obsess so much? Make a collage about your feelings? Try to relax? I KNOW how hard that is; I'm the queen of obsessing about my sessions!

I'm sorry you can't sleep. Do you have those relaxation tapes you can listen to? Or just soothing music or something? Can you tell yourself it's GOOD that you told your T, and you did not tell her too much. It bothers YOU but she's there to help you, not judge you for what you told her. It's a very slow process. I wish it didn't hurt so much.
