I'm sorry to hear that your group therapy isn't going well. I'm in a weekly therapy group, and it varies from being terrific to making me hugely frustrated and annoyed when I go there and it gets really disorganized and one or two members start crying as soon as group starts.

I'm sorry to hear that the group is pressuring you. That goes against how I think groups should work, and I wouldn't like it either. Is the group leader receptive to feedback?
