Can I do something!?!?

My parents got divorced about a year and a half ago. The divorce was supposed to be over a year and a half ago. If my mom wasn't the she is it would have been over a year and a half ago. My dad wanted it plain and simple. I live with my dad, my sister lives with my mom. He pays child support every month because he makes more. Well my mom didn't want it that way. She wanted both of us so she could have all my dads money. He make less than 28,000 a year. My dad owes half a million on our house as of now. My mom spends all her money she earns and gets on whatever my little sister wants. She's way past spoiled rotten and leave it at that. My mom doesn't even rent a house. She's living in a bedroom at her stepmothers. An now court order states I have to live wih her. My little sister is 11 and I'm 14 by the way. Anyway my mom knows if my dad can't have either of us he will move back to Utah where only a few family members (a sister and nephew) he has are left. I should also mention she put me in therapy for acting like a teenager... Which is retarded. And I have too many scars from when she beat me when I was little. My dad never hit me. Is there anything I can do to get the divorce over and live with my dad? How many sleeping pills will it take to kill my mom. I'm not ******* around. I'm dead ******* serious. She is a selfish *****. I also have a 12 gauge shotgun, ak-47, glock 17 9mm, and a lot ok hunting knives... Could these be useful? Or can I take this issue to court? Will I get what I want? Don't answer if your not on my side with this or you're gonna lecture me about something I don't want to hear... Well I'm mostly deaf so something I don't want to read... You will be reported because I'm not ******* around. Thx to whoever answers and I like it. Please also add anything I can do to piss her off. Thx ^,..,^
