How can i move out of home at 17?

basically my home life is really stressing me out, every night theres and argument until 4 in the morning and i have to go to school everyday or work on sundays, arguments will involve me if i try to stop them or tell my dad to go away or tell mum to go to bed, i have been told just last night actually how much they actually care about me, i really cant live here anymore because my sister and her boyfriend are saying thier homeless so they can get a flat so it will be just me and the two ****'s, is there anything i can do to move out and still go to school?
