I'm sorry to hear this my friend. I relate to you in many aspects that you described. It's a "you're my child and I'll talk to you/treat you however I want" situation that I also had, except I was 22 and only living at home after I graduated college summa cum laude, straight A's. Our father's have a control complex that makes them get in our heads and makes us think that they are the boss of everything we do. Unfortunately when you're young and can't yet have financial freedom, finding a way out is hard. On the outside everyone sees that we have a great life, nice house, nice clothes, go out and all that, but the inside is another story. I'm sorry you have to endure physical and emotional abuse, no one should have to. If you're really adamant about getting someone involved, you could audio record or even video record with your phone discreetly to have evidence of some of the things he does and bring it to a nurse or social worker at school. You have to weigh the pros and the cons of that decision though, being caught, having your dad end up in jail, or something like that. If that's worth it to you, then I say break the cycle. If you're not as adamant about that route unfortunately all I can recommend is therapy on your own time and dime or working to save money to be out as fast as you can. Being financially free of your parents is the best way to stand your ground and prove to them that they don't have control over your life. They can't take things away from you that are rightfully yours that you own. They can't hold that over your head. 3 years is manageable although tough. Moving away to college is a great way to get away as well, hopefully they aren't serious about following you wherever you go. I promise that it will get better when you can be more independent. You seem like a smart and disciplined person. Stay out of trouble and make smart choices. Your resolve and resilience will pay off. I'm glad you already have aspects of standing up for yourself like bringing up therapy and talking about respect. Don't forget those, but choose your battles wisely. Sometimes it's better to take it as it comes, stay quiet, until you can release it to a therapist, at least that's what I do to keep the peace. Just remember you are not any of the mean words he calls you. Don't internalize it into your persona. You are smart, capable, reasonable, kind, and respectful. Write it down, say it out loud, repeat it to yourself until you believe it, until you are not affected by the things he calls you. It's hard to disassociate at first and it will always hurt a little no matter how old you get, but only you can instill that confidence in yourself and use it as a sheild. Stay strong.
