Psych hospitals in the US, whether public or private, give you a lot of time and space to ruminate about your thoughts. Activities every hour, for about 15 minutes, then 45 minutes of nothing. Sometimes they'll let you watch TV. Sometimes they'll let you walk around the hallways. The orderly does 30 minute checks 24/7, jotting down notes of what you ate, what you did, what medicines did you take, what are your social habits, etc. There is a zero contact rule. You are not allowed to fight a staff member and a staff member can't touch you. But in their clause, they didn't say that another patient can touch another patient. So another patient can beat you up and all the staff can do is stand there and ask the patient to calm down, "please stopping hitting", etc.
It's like a watered down jail except you're paying a $75k bill upon release. 75k dollars for a person that could maim you because they didn't like the way you look or the voices in their head told them to hurt you. If I had to involuntary go in, I'm always on my guard. If someone came at me, they're head is going first thing through a window. Jail rules are in effect at a psych hospital. US has made it clear that they are not there to help you.
