Mental Hospital Question?

Ok so i'm 15 and i'm going in a couple of days. I was told that i should not bring any of my clothing because i will have to where theirs. I'm probably going to be on suicide watch because my parents think i want to kill myself but i don't and their probably going to say i want to when i check in. So my question is what will i be wherein for the week. Will it just be a hospital gown or if they put me on suicide watch will it be like something you cant hurt yourself in like one of those paper gowns from the doctors office :(. and whats suicide watch like. im like flippin out now and scared to death. i allow im if someone wants to talk to me but no creepers, sorry guys.
