Yep. Someone sits right outside your door all day, and is immediately available if you need to talk or cry. They're there for you when you fall asleep, and someone is there for you when you wake up. They provide the security of knowing no one is going to invade your room, and yet are far enough away to let you sleep and find some peace.
People do an amazing job recovering there because the stress of their lives is temporarily gone -there's no chores to do, they don't have to work, family is only there during visiting hours, and therapists are there every day.
While I'm the first to admit our mental health system has issues, and that many people don't get the help they need, those who do are usually ready to face life again when they leave the hospital, and ongoing therapy continues to provide the tools and resources they need to put their traumas behind them.

Also; I want to put this here because when Google indexes this, someone may find it needing help, so I think it's important:
