How can I as a 13 year old be emancipated?

I may seem that I am from the line of brats but how can I put it into words . Nevermind that! I am not really a normal child as it may appear to be when you look at m cover. I am feeling very much like all sanity has been lost for me . My siblings are the same but different. . Strange you say but you should see with you own eyes of my life sorry no vidio camera . My parent /mom usually beat me until a while ago I don't know why it stopped but the beatings hurt . Compared to the ones made by the man we know as father he was a brutall drunkard one time he beat me and my sisters with a metal flyswapper but he made one mistake he left cuts on my face they hurt when I went to school the teacher asked where'd you get that from my mom told me not totell he dad cuase he'd go to jail I did so becuase I was a dumb and ignorent child I loved him alote then so I made up the most terribal lie there could be ;I was dancing with my dog he got. Mad at me and scrached my face. I know she didn't belrive me I tried . Now they yell at me more make me feel as if I am in the lowest level there could be . You can say they do that cuase they love me but is hitting a child with a broom stick or yard stick a necessity For the child to clean their room? They make me sick the my core ! I hate them even when they Say I love you but your at fualt here fine ! What if I am I'm not the mph one who is the one who chased all this hatred and pain on me ? Not my school mates I didn't learn from you guys not the t.v. Not from outsiders probly like you but themselves you fight you show your hatred right there and then .
