Here in Australia, only around 3000 people a year commit suicide, out of a population of around 20 million. Suicide to me isn't really a sign of weakness (if that's what you imply), because if that were the case i feel the rate would be MUCH higher.
I'm not contemplating suicide, but i have lived all my life with CRIPPLING (and undiagnosed) mental illness, and i can tell you i'm truly in pain and sometimes in AGONY. Even though i can look all right on the outside, i spend some nights dissociating from EXTREME stress.
I just can't stand people saying that nothing's too bad to kill yourself over, because it just seems to be an opinion based on a narrow view of human existence.
While you bring up a good point, I just have to say that I don't think there is truly any reason to just flat out kill yourself. Life is full of stress, but that can be countered against with many,
many things. Like me, I used to think about suicide, but I went to games, I vented my frustrations onto the internet, I read books, etc. I think nearly every person that's ever committed suicide only did it because they either didn't look hard enough for that stress reliever or didn't want to find one. I can hardly understand the mindset of the latter, but the former just requires some calming down and experimentation. The only suicide I would be okay with is if death is already seen coming and it doesn't look pleasant, like being surrounded by hungry zombies. Picking the less painful way out would be a good idea.
Edit: And maybe something about my step dad's death
did affect me, because his reason, in note form, was to "get back" at everyone for some unknown reason. I don't understand that at all. I also view suicide as almost an insult. What if my best friend killed himself? Would I be sad? Of course, but I'd also be mad as hell at him, because that, to me, shows that when it came to either asking someone close for help and getting through it together or taking the "easy" way out, he ultimately chose to emotionally scar me, his family, other friends, wife, and maybe kids if he had them, for the rest of our lives.
