Emancipation??

I am 14. I live with my mom in Georgia. My dad is a complete jerk. He almost killed me when I was a child (he was going for a drug run with me in the car and we had a wreck). He got remarried and has two step kids. I love them and my stepmom,b ut i want to get divorced from my dad. Because I hate him, and he still hasn't told me himself about his drug problem (my mom told me). I have a stepdad, and I want to get legally adopted by him. He makes me come see him when I hate the mere thougth of him. i give up so much to "see" him then end up babysitting the whole time while he works. Can I get emancipated from just him, not my mom, and you know my beign 14??? HELP!!!
