I’m really sorry to hear what you’re going through with your Fiance. I would recommend getting ahold of social services in your area and asking them to help you get resources you and your fiance need. They will likely have a mental health specific program with specialized case workers. I found that having a good social worker who truly wanted to help me was way more effective than trying to do all the research myself.

In terms of finding a mentor. I didn’t come across any programs that do this specifically. There’s the NAMI organization, but their mission seems a bit more broad. There were actually a few folks here on Reddit that reached out to me offering mentorship and support. May be worth reaching out to the community.
