wish i was never born

i cant wait until the world ends, i've been really bad and done bad stuff from since i was little, im only 16 now. i think im getting karma or getting punished by god or something, im really angry because i see other people around me doing bad things and they are getting no punishment, how do i escape? i also hate people like being around them, my mum and sister complain im horrible and im evil because i never speak to them, i hate talking, also i thing my brain is ruined since i started smoking weed at 13, im worried there is no future for me? what the hell to do?
