Depressed..... iam on the brink of running away?

My parents program me as a robot, it is as if every move i make it is automatic. I do thinks to please my mom and dad. iam 19yrs old. Iam not allowed to wear sleeve-less blouse, go outside with my mom's permission(because my dad has no say), iam dating a guy that my parents knew about and liked and because they found out he is the son of a politician they forbid me to see him. Iam regularly cursed at for being on the internet and no guy not even my friend(including females) are allowed in my yard. Iam so fed up, i feel likea prisoner in my own home. I sometimes cry myself to sleep cause i truly wish i could tell my parents what is on my mind, but i was grown to "back-answer" adults. I constantly think of running away but refuse to because i would jeopardize my schooling. iam so fed up that i was i was as any of my friends because iam not allowed to go to parties or the movies. What should i do?
