Both gen pop and the prison psyched ward would hell.
At an older prison, in gen pop, you get to deal with extreme boredom coupled with an intense fear of violence, and in the prison psych ward, you get to spend the day in some dingy shit-hole drooling on yourself completely doped up on drugs.
They both sound like horrible experience. I mean what is worse, consciously living in terrible conditions or being so doped up that you don't know that you are alive?
