I did the support group (NAMI for me) as replacement for IOP thing. It didn't work too well. I needed so much more than a peer group could give. It was a last attempt to get something going for me because I couldn't get into an IOP since there wasn't one reasonably close to home and the only one possible did not meet my needs at all (they wouldn't let me see my own drs and that's an absolute requirement for me; nobody messes with my meds but my own pdoc or the hospital one who is in contact with her).

I can't see that working for you either, not the way you are feeling right now. Peers can't help with suicide or psychosis and you need help with both of those.
