When I was seeing T, she suggested that I find a DBT group. I tried 3 different groups while with her. The first and third group was really helpful. The second group, which was a process group and not a skills group, was lead by an incompetent therapist who let another client verbally attack me.

Both T and L have also been really supportive of me on these forums. They're all for any healthy way to get extra support.

Definitely try out a group. I don't think there's anything wrong with that. You could always discuss with your T.
