PLEASE HELP!! I really want to change my life into the better! I hate myself! PLEASE HELP!?

Your 13 and in your third year of highchool?!? okay well anyway. it sounds like your really want to change so here's my advice. 1st find out what you like/ who you are. once you find your hobbies then soround yorself with people who like those same hobbies that way your friends arnt just random friends, there the people you relate to and can relay on. 2nd calm yourself, when someones in your way you can politly move them aside. frankly it gets really annoying so if you just shuve throught them instead of saying "move b****" say "oh, im so sorry" as curisy. 3d stay away from people who gossip. they make the worst friends and they'd are bad people to saround yourself with. 4 just be nice when you do something mean apologize, but try to avoid doing that in the first place. you can do it if you really want to. and ur making a good choice to better yourself.
