There was a comment thread on a post from /r/morbidreality (http://www.reddit.com/r/MorbidReality/comments/1w6e9u/teenager_kills_himself_so_his_struggling_family/) that inspired this question.
I'd say this is a better place to ask this question than /r/askreddit because I feel that this sub can get deeper into the history of why we're so different.
It will be difficult to get into this without breaking the twenty-year rule, I suspect.
