This experience doesn't sound helpful.

I personally never understood group therapy. Sessions were about complaints and stern moral judgment from the therapists, with no solutions discussed. I was disapproved of when I quietly, modestly shared good news at the end of a session because I was out of step with the group's misery culture. The therapists ridiculed me for reading David Burn's Feeling Good and concluding I needed stop being self-critical. I was ridiculed again for NOT being critical of another member in a "describe him with two adjectives" exercise. The therapists were authorities on life: "You're unemployed because YOU'RE NO IN TOUCH WITH YOUR FEELINGS.

I don't know how group therapy is supposed to work. I've only seen therapists to do it badly.
