sweet baby jesus of hatred

So we adopted my sister back in fourth grade. So seven years ago. She was a little spoiled brat, but I had wanted a sister and I was determined to stick through it because she was my age.Well we adopted her and things were ok I guess. But she treats my parents like shit and all of us like shit. She thinks my parents pick on her most and that I'm the 'favorite child.' Which is complete and utter bull - I get in trouble just as much, if not more, than she does. Just because I was the first adopted and they are technically my grandparents doesn't mean that I'm the fucking favorite. Maybe if she wasn't such a stupid fucking self entitled bitch, maybe if she actually tried in school and didn't slack the fuck off and go party. Maybe if she wasn't a fucking fifteen year old fucking a 20 year old guy. Maybe if she wasn't a stupid fucking whore who thought she was god's gift to humans. Maybe if she didn't fucking use guys so they would buy her shit. MABY E IF SHE WASN'T SUCH A STUPID FUCKING CUNT. 
JESUS CHRIST PARDON MY LANGUAGE BUT GOD FUCKING DAMMIT I CAN'T EVEN STAND HER SHE'S A FUCKING BITCH TO EVERYONE AND THINKS SHE'S A FUCKING PRINCESS. SHE THINKS TAHT SHE DESERVES TO BE HANDED EVERYTHING ON A SILVER FUCKING PLATTER AND SHE'S A COMPLETE AND UTTER FUCKTARD TO ALL MY FRIENDS CALLING THEM FREAKS AND OTHER SHIT LIKE THAT. SHE CAN BACK THE FUCK OFF JUST CAUSE SHE'S A RAGING PIECE OF SHIT DOESN'T MEAN SHE IS BETTER THAN ANYONE. IN FACT I THINK SHE'S BELOW ABSOLUTELY EVERYONE. SHE TREATS PEOPLE WORSE THAN ANYONE I KNOW AND SHE DESERVES TO HAVE SHIT PLOW UP IN HER FUCKING FACE. I CAN'T WAIT TILL SHE GETS TOT HE REAL WORLD AND SHE GETS HANDED A HUGE FUCKING DOSE OF REALITY. 
She bitches that our parents are so unfair and that she never gets what she wants. Excuse you you fucking skank you think you're so fucking entitled? All you do is sit and fucking whine until you get your damn way. You a fucking terrible excuse for a human being and I hope you spend your entire fucking life in a fucking trailer park with not a damn dollar to your name with all you illegitimate fucking kids. You're a stupid piece of shit and I couldn't fucking care less if you went and lived with that pathetic excuse for a 'boyfriend' that you have. I fucking hate the everliving shit out of you and I hope you fucking fail in life and come crawling back expecting help cause you won't be getting any you fucking cunt. I can't even fucking stand you and I fucking hope shit really hits you once you move out and 'never look back' as you always say. Stupid piece of fucking shit fucking holy fuck i can't even fucking stand your stupid fucking face you fucking fuck sdrjoisajhldkfjawopeiurfnasd;l kFUCK
