What is the first step of the emancipation process?

I am turning 17 in May and I really really really want to get emancipated. My mom is cool and all but she can really suck. Every time I ask her a question/ask for her reasoning because I think she's being unfair she raises her voice and goes "Because I said so" She also curses at me and threatens to use physical violence on me like punching me (She's not actually going to, I know) and yeah every time she or my dad hurt my feelings, I harm my skin in response. My dad is much worse than my mom. He is more toxic and curses way more, yells at me over small stuff, and considers me trying to defend myself as disrespectful. Then when I cry he calls me dramatic. He doesn't live with my mom and I right now because he works in another state but when he's home I hate it. When I first started cutting he slapped me, told me I was gonna go to Hell, and just made me afraid. My mom also threatens to send me away to a psych hospital and will be like "Its your fault you're going" and yeah I just feel like I need to get away from them now. I can't wait another year. My only issue is when I talked to my mom about emancipation once she started yelling at me, saying no you can't, cursing at me & telling me to get out of her face, and slamming stuff around. So yeah good luck for me I guess
