P.S. What I didn't like about the original article is it made it sound as if the feelings that lead to suicide are some sort of effete existential angst, and therefore rather mysterious, while in reality -- at least for me -- the feelings were just HELL ON EARTH.

Anyone who has any inkling of how much real tangible pain your own brain can put you in, would never question why someone might commit suicide. There are times when not doing so requires incredible strength and perseverance. Either that, or not even having the wherewithal anymore to take your own life.
