Institutionalizing the kinds of severely mentally ill people who would benefit most from this kind of care is practically impossible, thanks to efforts from civil rights activists decades ago. Resources to help homeless with mental illness exist, but sadly these programs are all voluntary and have no real way to make someone follow through with treatment.
I was literally tortured in a privately run psychiatric hospital three years ago that I was forced to stay in for 10 days because of a misunderstanding. 10 days is the maximum Disability will pay for inpatient. Suddenly after 10 days I was better even thought I was fine on the first. I spoke to a doctor twice for a total of 10 minutes they whole stay.
We are not stupid, the system and society treats us like garbage. And when we just want to be left alone and be simple and free they pass laws and raise prices on everything.
At no point in history have we ever had a mental illness treatment doctrine that we can look back on and say "that was a good thing we did, go us". I happen to believe that the present day will be viewed upon no more favorably, what with our pills by the pocket-full and unregulated medical advertisements on social media. (Instagram sponsored content would seem to have the whole world believing they are in desperate need of antidepressants and Adderall, paid for by... the shillers of antidepressants and Adderall, how interesting.)
The fact that I could not get my doctors to look at my mental illness as an immune disorder (even after I was diagnosed with Lupus) as being the cause of my mood disorder tells you everything about how ignorant practical care is for the mentally ill. I just had a psychotic break after catching COVID as well.
Mental Illnesses are immune disorders.
These things aren't even available to people if they want them.
