My guess about the fascination with celebrity suicides is linked to some supposed satisfaction we'd expect to have in their situations. I'm guessing in a lot of ways satisfaction, like weight and credit goes faster and lasts longer when it's in negative territory (negative, so to speak).
Hypothetically:
Of course some other loser, nobody slob like "myself" would kill commit suicide. I know the kind of crap useless life I lead and it's amazing I haven't done it yet.
Confession: I'm about to start drinking. Small office, flask at work. It's the little things in life.
