I'm really sorry to hear that, I know it must suck, when people do stupid things like that,its so selfish because they dont realize that if anything happens to them, yes they are hurting themselves, but they are hurting everyone else at the same time. my 4 month old baby sister was killed in an accident involving a drunk driver, i was around 7 or 8 at the time, her car seat wasnt completely secured all the way because they werent driving too far and it was late at night. my parents still, to this day, have never forgiven themselves for not securing her car seat.
this is a bit off topic, but suicide is also one of the most selfish things you can do. it's like saying I hate my life so much, and I can't take it anymore, so i'm going to make it a living hell for everything that has to live without me everyday.
