What happens if i'm hospitalized for anorexia?

So here's a brief explanation: i'm 16 i weigh 100lbs and i'm 5'4.5. Anyways my psychiatrist told me that if i ever go under 110 lbs he will have to tell my parents and possibly hospitalize me. I've been an outpatient for almost a year and i didn't get better but i'm actually willing but my psychologist keeps focusing on my issues with my rather than my body image issues because the last i went to her office i was at a healthy weight so she thought i'm fine. Anyways i haven't gone to my psychiatrist since April but my parents want to schedule a new appointment next week because they want to talk to him if i should stop my anti depressant or no. However i'm very nervous and scared but i'm willing to take recovery but ihave a few questions: if i'm hospitaliZed what kind of therapy ill be taking?(group therapy, individual, music.) will i be allowed visitors? Will be allowed to have my iphone, ipod, laptop? What about school? I'm starting school in 10 days. If i request that i don't want any visitors will they do that? Keep in mind i'm going to be in a hospital not a rehab center. And please share your experience and tell me more about it.

I have no experience of that, but i do know that you will be allowed to have visitors, it really helps./
