I cannot stand my little sister or mom?

i hate my little sister.she's in 5th grade, 10 years old going on 20 apparently.she bosses me around even though im 14.shes daddys little princess,moms best shopping buddy,and can have all of her bratty little cheerleader friends over all the time.i tell my parents this but they don't listen.im a freshman playing varsity soccer and jv captain,but thats not as important in our house as jumping and screaming and squeaking like rats in front of a crowd.i don't get the respect from her or any1 in my house that i deserve.they always take my sister's side and i hate her.don't tell me i don't cuz i do.if we go out to eat or if she wants something, i usually pay for it.she wants a cinnamon twisty at taco bell,nicky buys it for her.no one asks me to do it i just do it because i know it's being a good person.she thinks she's so funny too and that pisses me to the point i want to punch a baby-thats right.AN INFANT!!!i always spend all my time with my friends and out of my house because i can't be in the same room as either my sister or my mom(dad's cool the majority of the time) for 5 minutes without a fight breaking out.then i get sent to my room,i can't use the phone for a week,i get yelled at and im sick of it!!!how can i show them how they make me feel?im a 14 year old guy im not gonna cry and throw a fit to get what i want like my bitchy sister.each time i say anything it's wrong and im just a smart *** and im tired of it.what can i do?they dont listen to me
