It’s a big problem. 90 days might help, however. I live in Florida, where you can only get 3 days, and my friend’s son went in and out for 3 days here, 3 days there, until he finally killed himself after his last 3 day committal.
I think a judge has to intervene after three days. But the hospitals don’t want to go through this and in any case the judges usually release them. So then they can go out and kill themselves or somebody else.
Individuals usually get the three day treatment after an “event”. The mission of the hospital over that period of time is “stabilization”, which often includes medication to the point of a catatonic state. The patient is sent home and then whatever happens, happens.
