my mother committed suicide
i have made several attempts myself with varying degrees of sucess

when robin williams died there was a whole discussion i was part of about whether or not suicide is a selfish act. while we all agreed that it is often an act of desperation i was one of the few who thought it to be selfish. not in the hahaha i win kind of selfish way but in the not having regard for those around you or the empathy to understand what youd be doing to them.
saying that, as i mentioned ive also had attempts. sometimes you cant stand up for the greater good and you have to do what you think is best for yourself.
but having lost my mother to her own hand i will NEVER think that suicide doesnt cause severe trauma to the survivors.
