I guess it depended on the group. I like small groups and an involved facilitator. I've had groups like that a couple of times.

The NAMI group I went to was fine until they talked about religion. The DBSA group didn't do much until a manic guy came in at the last minute. Both involved long drives at night. The DBT class I went to was fine until they changed facilitators and almost doubled the class size. The new facilitator was condescending and kicked out people who weren't on time. So that was it.

I would like to try again, but maybe another time.
