Sunrise's advice sounded good. To put in a little good word for group therapy, you can see people making progress in our group, and it does take time. One girl was in the group for 5 years, and apparently didn't talk much for the first four! She found her voice in the year we overlapped and has just left to try out getting a social life.

I can ask others questions, but find it really hard to talk about myself, which mirrors real life. I'm (Edit: still!) working on that. I know how hard it is to speak up, especially when the pressure's on. It's easy to be down on yourself too, but if you can give yourself time, and ask the others to give you time maybe that would help. You said that previously you even looked forward to it. That could happen again when you're feeling less down on yourself.
