Supporting myself

Does anyone have and suggestions on how to support myself? I can't 
live with my mom anymore. She yells at me about everything. My friends kept saying my mom was cool. Tonight they slightly saw the truth. She's never really home either. She's always out with the guy she's seeing, working, or at school. When she is home she pretty much studies and yells at me. I really want to get emancipated but I'm not sure how to support myself. If I'm here any longer I'm not sure I'll be alive for much longer, she's affecting my mental health. My parents have been spilt since I was 4 (I'm 16 now) and I haven't spoken to my dad in 3 years. He's neglectful. So I can't go to him. I don't have any siblings I can go with. I'm kinda on my own here.
