OP here. I told my therapist during individual session that I don't feel like I'm getting anything out of the group and why. She said there is no pressure to attend and if I don't feel comfortable then I should feel free to quit. But she asked me to give a bit more time, maybe a month before I decide. There should be one more person joining, so there will be four. Still, kind of small.

I was even more detached from the group this week. One guy was raving about his family and financial problems half the time.
