My primary years are filled with isolation and bully too, but i just dont care, more like stop carring of anything, it starts out as ignoring their words and actions, then bad grades i dont care, injuries i dont care, getting to troubles i dont care, being a bad person i still dont care. If i feel like it Ill annoy them to death. Like being an loud idiot mentally retared they say i was, I yell and hit and annoy them to death
