How much do you have to hate yourself to want to just wipe yourself out?

Ten little soldier boys went out to dine;
one cheked his little self and then there were nine.
Nine little soldier boys sat up very late;
one overslept himself and then there were eight.
eight little soldier boys climbing up to heaven;
one fell down and then there were seven.
seven little soldier boys chopping up sticks;
one chopped himself in half and then there were six
six little solider boys playing with a hive;
A bumblebee stung one and then there were five.
Five little soldier boys on a cellar door
one fell in and then there were four.
-Suicide Notes by Michael Ford

First you have your generic depressives. They're a dime a dozene and usually really boring. Then you've got the bulimics and the anorexics. They're slightly more interesting, although usually they're just girls with nothing better to do. Then you start getting to the good stuff: the arsonists, the schizophrenics, the manic-depressives. You can never quite tell what those will do. And then you've got the junkies. They're completely tragic, because chances are they're juswt going to go right back on the stuff when they get out of here.
"So junkies are the top of the crazy chain." I said.
"Uh-uh. Suicides are." Sadie says
"Why?"
"Anyone can be crazy," She answered. "That's usually just because there's something screwed up in the wiring, you know? But suicide is a whole different thing. I mean, how much do you have to hate yourself to want to just wipe yourself out?"
