Am I wrong? (Need Family guidance)?

Ok background of my life first... Im a 18yr old male grew up with my dad in the USAF and mom working full time till I was about 7 1/2, never had alot of money and didn't quite fit in... then my brother was born, I never see my dad he's a computer engineer now and hardly ever home while I grew up. Mom switched occupations to a stay at home mom as soon as my brother was born. Now were upper midle class and my brothers growin up with 2 parents when I grew up with a daycare and has things Id never dream of at his age.... His relationship with my parents is always fine but me and my father have alway butt heads, my father has always had a weird relationship with me and the only way I can describe it as is he dumps his child hood stress on me, whenever he needs to I'm the scape goat to yell and scream at etc. ( not the only one that sees this my mother notices to ) so here I am with my predicament my parents accuse me 24/7 that I absolutely hate my brother and that I am so spiteful towards him, like how I never give him a hug or a kiss etc. ( btw all of this is **** they put In his mouth because I watch my brother all the time when my parents are out of town and me and him are like two peas in a pod) but back to this.... Were 7 1/2 years apart are we really supost to get along to the point I do Everything with him??? I hope not!!! I have a life! I'm preparing for college!!!! Idk Wat they want out of me I just had to vent because the yelling and screaming all the time is really taking a toll on me mentally well thanks for taking ur time to read this and any advice is much appreciated
