That's horrible!. I've been in group therapy and I've also been attacked be groupmembers. Most of the time we were with 10 people and 1 or 2 T's. The whole year there was always 2 or 3 persons who were like the loudest of the group. And many times they had something to say to one of the others in the group. And it wasn't something helpful, but more something they were annoyed by. I was one of the quitest of the group, but was one the reasons I needed therapy. I had social anxiety and the group knew that. And some could be so mean to me and really attack me. It made me feel so bad and I got even more afraid of talking.

I don't know what you can do. Maybe talk to your T about this? What those two group members said, I don't agree with them. You don't have to put up with her behaviour just because she's been having a hard time lately. Everyone in group has, otherwise you wouldn't be in therapy.

I hope next session will go better for you. And try to not let what she says get to you. I know that's very hard. But it says more about what she's for a person, than about you.
