I have a very close friend that has been in the deepest troughs of depression for the past couple of years. They live about an hour away, so though my wife and I try to physically show up to support them whenever we can, that's much less often than we'd like. Their support network is thin, and day-to-day basically consists of only their partner, with whom they live, and who is visibly fraying at the seams.

This person (I'll just call them John for the sake of readability) is currently on medication for their depression and OCD (I'm nearly certain it's Lexapro, can't remember for sure) and has on and off therapy, though they often find themselves at odds with their therapists' perspectives. Some of this is because it feels like the profession has been flooded with folks who lack experience with patients with severe chronic mental illness, and some of this is (I suspect) John's illness distorting their thinking, leading to frustration and anger in the moment that doesn't make sense in retrospect.

John had a particularly bad day yesterday, and after I spent some time with them, we started talking about how they felt like they needed considerably more support than they were able to get in their current situation. Unfortunately, the only option he was aware of was "group homes", which seems like a pretty broad term and I don't know much about what they look like (or how successful they are at helping people like John).

I'm trying to get a sense of the spectrum of options available for people like John who are suffering from severe chronic mental illness. On the one end, there's what we're doing now; regular psychiatry and counseling, and on the other end, I guess, is involuntary in-patient behavioral health/medicine clinics. Being involuntarily committed to such programs has been a source of trauma for them in the past, so I'd like to avoid anything even close to that end of the spectrum, if possible. I know that there are, for example, 90-day rehabilitation centers for folks with substance use disorders (I have a family member that found a lot of success at one of these), but do similar programs exist for folks non-substance-related mental illness? Does anyone have personal experience with any of these programs?

Thanks in advance to anyone who takes a moment to read and share their thoughts; I know this is a really challenging topic.
