Tired of dealing with my problems-FAMILY ISSUES?

im 17-male. my parents never let me go out places......i dont have confidence in myself......i never had a gf or kissed a girl...obviously a virgin and my grades aer bad. My parents keep yelling at me and they are penetrating my emotions until i cant take it anymore...the way that i am now, is not how im supposed to be. because of them, i became bi polar and over emotional. i became more lazy and depressed. my mom always tell me stuff like your a disgrace, no one wants you, go live on the streets, i can sell u for a dollar. its always an issue to go out places with my friends. i never hanged out with my friends so i cant really call them my friends cuz my dad makes it an issue when i wanna go out. when i wanna go to a party my dad says no you might get shot...i wanna go party in the night and say the same thing. my fam is the type to be and stay on the good side of life. i dont wanna do thati wanna be a normal teenager and hang out and do good in school. i feel like im going to skool for them not for me thats y i do bad. my dad has a temper and is from the military and he used to beat me and put me in check. now he has cancer and has a swollen leg. honestly if he ever touches me i'm gonna shed blood to his face because my anger has been building up with my parents. im a fighter also and i love to fight. idc if i loose i just wanna knock him out. he did many wrong things to me and my things, broke my ps2 2 times!! and ps3 2 times! but the second time it didnt break he thinks its broken lol. they keep me home all day and he makes me do house chores all day, dishes, laundry and to help him in his garden. He says its to better me but how when thats all i do. i live such a fragile life that weed makes me escape from everything. my fam found out, and it spread throughout family across country and across the globe. How the f*ck did that happen and what was going around my fam is that i was doing crack, and heroin. I need weed to survive on...and my parents look at things differently. They always say go help them with work but i never go out. My dad says dont answer back in my mind but i always do cuz i will never be llike my parents. When i leaev this house, they will never hear from me again, i told them that, and i said i will not be wat u want me to be and i told them i want to be a pornstar, they have a specific way of life that they want to live to, i wont do it , they say when they get old i will take care of them i said hell no im putting them in a nursing home, they always make me go to religious ceremony's and now im athiest cuz of them. They think they follow god but they to do wrong things. I dont have enough freedom. Im very handsome and i like girls but when a girl looks at me i wont talk to them cuz i dont have confidence in myself. this happens alot btw. i got beat up in middle skool until i went to the hospital. my bully made my face covered in blood then took a picture of my face. i didnt fight back cuz i wasnt confident. my parents held me back of so many things, including my brother. one time my parents made me go to a religious ceremony and my bro was annoying me and i said f*ck you in fron of everyone and i punched him on his head in fron of everyone. anger is building up that idc where im at. What do i do
