why

How come i ruin everything? it makes no sense, i really cant stand how i just touch something and it brakes or i open my mouth and people hate me. Will i ever under stand? will anybody notice me? what will happen to me? why does my world crash down? why do people call me stupid, not good enough? because now thats what i call my myself, because it seams i messed up my life trying not to. that no one cares. that no one is there, i made them run away...  now i'm alone, and scared, and i dont know what to do...
