I've been to a number of support groups, and they've mostly been pretty helpful for me. A couple weren't, and there have been a couple of scary times -- the depresion and bipolar groups, if some of the bipolars aren't well stabilized. (One guy came in depressed and switched in the group -- we had to leave early, because he wouldn't leave and couldn't control himself.)

I also go to an eating disorders support group, which can be weird for me, because they're mostly all bulimic, and I'm not. Still, enough of hte issues are the same that it's still hepful.

I guess the one thing I'd say is that you can say that your own issues may not relate to depression, if that's how you feel. I've seen that dynamic, and it is tiring, if you don't believe that everything comes back to depression. Try a few times, maybe, and see how things go. Maybe it'll get better as time goes on.
