Not me but my fiance, it was the only thing that brought her out of a months long paranoid psychotic episode, intensive medication, involved observation, multiple times a day therapy sessions with actual psychiatrists etc. She hated the experience, it’s like jail but with softer furniture. It took about 2 months before they were comfortable signing off on her release.

This kind of mental health rehab doesn’t seem to be what everyone else in here has in mind though, everyone else just seems to be talking about going to counseling rather than actual inpatient treatment
