I just got accepted to a boarding school!?

I live in washington and just got accepted to a boarding school a few states away, and I was wondering what is it like? I am really excited it looks like a real good school, but I am extremely germ phobic (what should i do if one of my roomies gets sick?) and the bathrooms have stalls in the dorms... so how am i supposed to go number "2" without others hearing or walking in on me (gross i know) any experiences with boarding schools, like homesickness will help. thank yous :3
