It depends on where you are. I've lived in several. Most recent was a state facility and it honestly wasnt that bad except for the expectation to "fix" me. I got to work, do some crazy art and crafts, horseback riding, free time outside, shopping, trips to the mall. It wasn't bad at all, except that I knew when I got out the world would be the same and I wouldnt fit into it. Sure enough, when I got out, society was even crueler.
Let me also state that I've been in some where I was thrown in padded rooms, tied down and sedated.
