Aggravating Schoolmates

It is something wrong with me when almost everyone in my grade don't like me? I mean I haven't done anybody wrong, it's just that I've gotten into it with people and people that associate with don't like me. I kinda care but then I don't. I mean I'm a junior, so I should be preparing for the rest of my life. I don't have time for the non sense and what not, but they can't seem to understand that. If I don't like someone I'm not going to talk about them or give them any power because 9 out of 10 they're not worth no air. If I'm not friends with someone I can most definitely just leave them alone and keep moving on with life, but at my school the females there can't. They wanna dwell on every little thing and want to be so messy and caddy all the time. It's almost as if they're stuck in their little girl ways and don't want to grow up. They stay worrying about me all the time. Do you guys have tips for ignoring people's comments and remarks because I'm a very hot headed person and can pop off easily. I'm also in the process of changing myself and this is a big part of my transformation
