My parents are ruining my life...?

I swear, drink, smoke and party. And yet my parents still hate me! I don't know why they don't understand...my friends do it! I've also gotten pregnant 2 times, and was responsible enough to get an abortion, WHY DON'T THEY TRUST ME? Seriously, they even threatened to put me out on the streets, when my drug dealer Josiah came to my house so we could both smoke crack together...honestly I'm unique from other kids, how can I make my parents care? :((((
