Are these support groups or therapy groups? There is a difference.

Therapy groups require clients to agree to confidentiality of other members, are led by licensed therapists, and are processing and therapy focused. I've found great benefit from well-organized, well-led group therapy;however, not all group therapy situations are created equally in quality (I've seen both).

Support groups are often run by organizations like NAMI or BPDSA and are more socially oriented with an element of psych education/advocacy mixed in. I've honestly never attended one; I've found support in small groups that are focused more on personal interests and those have helped me become more socially comfortable and additionally have helped me find sources of support beyond therapy.
