I don't want to hurt my parents, but I need to leave at 18.Does this seem like the right choice?

I’m looking for some very helpful advice and guidance. Mostly positive. My situation is this: ever since I was a freshman in high school, I’ve wished to move out. Couldn’t wait for they day till I turned 18. (I’m 17 now, 18 in three weeks). I can’t stand my home life, and it’s getting to the point where I feel so worthless and my self esteem is shot. My dad always controlled every aspect of my life. Till this day I’m still not allowed to date. He gave me back my phone and specifically said “no boys” like I’m 10 years old. I’m not allowed to have a job because he insists that he has to drive me everywhere. He won’t let me ride with my friends. If he doesn’t approve of someone I’m friends with, he won’t let me hang out with them, or he’ll say mean things about them. The only miraculous times I can spend the night at a friends house is after he’s background checked their parents. I’m not allowed to be in a sport because he doesn’t want me to loose focus on school or start dating. And if I’m in a sport, it’s because my brother is in it too, which he can spy on me. I’ve never been to the movies wit my friends, never went bowling, or swimming or anything like that. I feel like I’ve been so deprived of normal teenage privileges. 8 months ago I got in the most trouble I’ve ever been in in my life. I snuck out to hang out with my boy friend and got in trouble with the police because I lied about my name(cause I was so scared my parents would find out). And till this day, whenever he is mad at me, he brings it up. Calls me “slut” “whore” everything you can think of. He’s so persistent on thinking I’m going to move in with my “baby-daddy”. He has no faith in me. And he unsupportive of me going to a dorm room for college because he doesn’t think I’m cut out to handle the dorm room atmosphere, and thinks I’ll end up pregnant. He makes me feel so worthless and incapable of doing anything on my own. My mom knows how he is, and she knows that I want to move out, but told me to that “I won’t make it, and to stick it out till college” I just don’t think that I can anymore. My question to you is: I’m planning to pack up all my things on the day before my birthday, and right as the clock strikes twelve, to leave out my window and be gone. Don’t worry, I have everything planned out. I have a close friend who is planning to let me stay with her, her mom is welcoming and doesn’t mind one bit. (I still plan to go to college and get a job ASAP) It’s not like I want to get out to go party and do bad things. I feel like I need this. I just want to know if this looks like the right choice, the smart choice, and okay thing to do? Also, how should I go about this? Tell them on my birthday that I’m leaving and cause a huge nasty fight? Because my dad will say the meanest things, and they will try giving me the biggest guilt trip of my life. Or, leave in the middle of the night, write them each a letter explaining everything, and avoid that fight? I know I will have to face them eventually, but I’m afraid if we fight before I want to leave, that they’ll talk me out of it. I just want to thank you for reading all of this, and all advice is very much appreciated.
Sincerely, fightforfreedom
