Im sure if u take enough of the shit it will kill u. Im not trying to tell u what to do, thats ur decision and nothing we can say can stop u. But dont kill urself, nothing is worth killing urself over. If u seriously think u have nothing to live for and are really thinking of killing urself just do sumthin else. Take a trip to a far away country where u can get away from most the shit, go deep in the jungle and live with the tribes or sumthin. Killing urself is a very very last resort, and shouldnt even really be considered a option. Just dont do it. find sumthin u like to do, theres always better days ahead u just gotta deal with the shit and be patient.
