boarding school advice?

I start private boarding school this September (not because I'm a bad kid, it's not that type of boarding school) and I'm SO nervous. I'm also happy at the same time because I really want to just move out of my house *~I'm going into grade 10 btw, and don't mention that I shouldn't be happy to leave this soon lol if you knew my family you would understand~* ANYWAYS I'm excited but don't know what to expect because I've been in public school my whole life?? does anyone have advice I WOULD APPRECIATE IT SM
