Ugh. I think you're brave to go to group. This is exactly the sort of drama that makes me crawl back under my rock at the mention of the words "group therapy."

I should be kinder--"Drama" is a pretty dismissive way to describe someone else's pain, but still...I couldn't do it, personally.

Is this group helping you? It seems like you've had an awful lot of trouble with it, from other group members to the group T. If it's helping, or if you think it would be beneficial to work through these problems, I'd say keep chugging through.

If not, drop it. Your primary T said you were free to, right?
