Help me.... Stress getting the better of me?

My life sucks...And i mean it. I'm stuck at home on weekdays with a mother that doesn't give a crap about me.... She always nags and threatens to punch me and beat me up. She says i don't respect her but it's cause she doesn't understand me... I don't actually disrespect her. She just doesn't know how to listen and jump to conclusions to often. Then when i'm at school it's the only way i can escape from her... I have a lot of friends but i just really want to be alone... Not everyone at school actually gets along with me and if i mean don'tr get along it's usually i make their lives worse or it's te other way around, I am becoming a mean person cause of this and she still blames me for being the ******** everytime we argue. I know i'm nothing without my mom, She feeds me and pays for everything i live on.... I just really need to get away from all this bullcrap... I drown in my hours on the computer... I drown myself with technology to escape but it still isn't enough... She tells me i'm not doing anything in the house but she doesn't tell my to do anything anyways! And there's no point trying to talk to her cause she's gonna ***** slap me anyways.... She never gives me a chance to talk... She never tells me what i do wrong and she bottles up her emotions and just explodes at me. Some people at school think i'm weird... I'm kind of a bully but not that much of a bully... I just am very mean when i talk, I hate this.
