Keep in mind that high school is not like the adult world, it is a "Lord of the Flies" kind of world where there is a lot of immaturity, cliques where the "in crowd", mainly jocks and preppies think they are better than everyone else. I was also bitter about girls in high school because most of them would rather date the arrogant jock or tattooed troublemaker instead of the smart nice guys. Remember that once you finish school and enter the real world, you will meet lots of mature, kind people and I think it will improve your attitude not only towards women but life in general. Good luck.
