I (17F) want to live with my mom but my dad has custody. Throughout my 17 years of living with my dad it's just been horrible. he's manipulative, mean, he'll scream and yell and have me screaming back to the point i'm about to pass out on the floor. They've done so much wrong (that i think personally) and my mental and emotional health has dwindled so much. My step mom has touched my chest thinking i was hiding a phone there, when it was obvious nothing was on my shirt, my dad has kicked punched and slammed doors. They've called me a slut, garbage, said rude stuff about my mom in front of me. When i've needed help regarding school or the kids there he just tells me i have to deal with it rather than helping taking more action. they've recently tried admitting me to the hospital because im almost 18. it's just overall my emotional and mental health is so bad and i understand i only have a bit longer until im 18 and can just get out of there, but idk how much longer i can do it. i have untreated illness because they don't want to help and my mom is going down thursday to file for emancipation. Im supposed to go back to my dads house today, but if i refuse and he calls the cops will the force me there? if i explain to them what the situation is and how she's taking me down to file for emancipation soon? im scared to talk to my dad because he'll jump the gun get a good lawyer and screw my mom over, i just don't know what to do.

UPDATE: i ended up texting my dad that i personally was refusing. he mentioned calling the cops and all this other stuff, but i told him to do so because they won't force me to leave. then he said if i wasn't home by tonight he will go to the courthouse tomorrow, i said to do it. so me and my mom are heading down first thing since she works in the courthouse, we can get into the building and wait outside the custody part of the office. When it opens we have the papers already filled out before he can get there first. Since then him, my step mom, and my grandma (his mom) have tried guilt tripping me, saying things like "you're tearing this family apart" and my dad saying stuff like "i've raised you for 17 years...". then he tells my grandma, who wanted me on her phone plan, to turn my phone off. so i have my old phone that im switching over now, and will get my own phone plan sometime this week. thank you all for the tips and advice, it helped a lot and i have already put my foot down and gotten farther, somewhere i've wanted. thank you 🙏🏻
