Why does no one like me..?

i have friends but it seems like everyone else hates me. i try to be nice to everyone but im quiet and i guess people dont like that. i get straight A's but i dont brag about it or even tell anyone cause i think being smart is just another bad thing about me..i dont really follow what everyone does and kind of do my own thing. i listen to what i like, watch what i like and like to wear sweatpants and hoodies and sometimes jeans and tee shirts. i dont really have designer stuff. and i dont party. but only cause i am so focused and i dont really ever get asked by my friends to go out.
