Is there a way I can leave my parents?

My parents have been mistreating me since I was young but recently it's not just verble abuse it's physical to. My mother punched me twice in the face and almost every fight slams me against a wall or to the floor, I rarely fight back because it only escalates, my clothes are rarely washed and I only have one bra that doesn't fit me because I've had to use it for years, she constantly screams that I'm useless and her biggest regret is having me, my dad used to be on my side but he is almost as bad as her Now the other night trashing my room and calling me the c word just because I had a headache and didn't want to go out for tea. I'm currently 15 and I know that somedays like all teenagers I can be a brat and not want to do the dishes or something like that but my actions shouldn't worent the reactions I get, I wish to know if there is a way I can become emancipated or adopted out because this is unbearable.
