@Joshx,
I'm having trouble following the chain of events here. Why did you call the cops? But then before that, you say you were picked up...?
I have no idea why you were in a hospital for 6 months for what was, perhaps, an involuntary commitment. I highly doubt it was just because you were barefoot. And if it was about the fight, it was probably for more than just yelling.
But I am not a doctor, and you're entitled to medical privacy. You don't have to write that here if you don't want to.
Of course, you don't have to watch wrestling if you don't want to. And, you don't have to hang around with them. Practice saying, "Sorry, not interested." Or "No, thanks, I've got a book I want to read."
It is against this site's Terms of Service and rules to provide medical or legal advice. All I can really tell you is to try to get along with them better, and plan on a way to find work so you can afford a place of your own.
