Family probs please help duno what to do

Hey, my name is ashlee. I probably already wrote a post like this i don't remember but im 16 eyars old, i live with both parents and 2 older bro's and a younger sis. When ever i'm at home i feel like an outcast. my bros n sis stick together through everything and im always left out. My parents give them what ever they want and me i have to work for everything.(not complaing because i know nothing should be handed to you). but my oldest bro is 22 and my parents just hand everything to him and my sis she gets what ever. but the main reason why i'm writting this is because i always end up going to bed every night crying wishing i was out of this house. i get into countless amount of fights with my brother (yelling and fist fights) and my parents are always on his side and always ask 'whats wrong with you ashlee'. nothing i ever do is good enough i always get blamed for everything when im home. please give me some advice on how i can put up wit this for 2 more years please. i couldnt write how bad it really is for me because it would be too much typing but please any help would be great.

A bit more info about the sittuation..give an example of a time when this happened. Perhaps this is just jelousy...?

A time when I got into a fight with my older brother was just today. He asked to check something on the computer so i let him on then he asked to stay on, i said in a bit. when he got off he threw the chair at me so i told him he can wait a bit longer now because i can't stand the way he treats me, he flipped out and hit me. i called my mom who took his side and asked what was wrong with me...

hun atleast for u its 2 more years. me its 6.
