So im 17 and my sister is 19. I live at home in northern california, and my sister lives most of the year in Canada because she goes to school there. Ever since she left for freshman year my parents have been harder and harder on me on everything whether it be cleaning my room, or academic studies. Whenever she comes home to visit my parents cater to her every needs, and expect me to do twice as much work as her even when she is sitting on the couch watching tv, and im studying for a big math test. what really set me off was a couple of days ago they all planned to go out for a nice dinner, and meet some family friends who i know pretty well for dinner, but i wasn't invited... and all my dad said to me was "are you okay with that?" and i just played it off like i was busy but i was actually really hurt. my sister is their idea of a perfect daughter, dresses normal, acts sweet to everyone but me, does good deeds only to receive attention. me on the other hand i listend to a lot of hardcore music, im not a follower of the main crowd, im really shy at first(and they think im anti-social), i tend to just wear blue jeans and a t-shirt wherever i go, but i work hard in school and im trying to get into a good university, but they dont really notice. im getting really frustrated now because i feel like im just getting shoved under the rug because i hurt my family's image and i just dont really know what to do at this point
