Yep, and that's the not the worst of it. You get checked on every half hour or so, and they might well walk in on you when you're using the bathroom if you don't reply to them when they want to know where you are.
A legal document has to be signed for you to walk outside the building, and they have to note what you wear before you go out.
Even if they agree that hospital is making you worse, they keep you in, and they could have you sectioned indefinitely and you wouldn't be able to do anything about it. Except appeal the section, but of course the people there will want you kept in unless you seem content.
You have set bedtimes there.
Also, no WiFi.
