Apis here. That post was probably a joke.
If it wasn't, the person likely isn't really suicidal over grad school apps. That kind of thing doesn't happen unless there's existing, underlying problems: depression, bipolar, borderline... stuff like that. Chances are, even if they got into a great program, they'd still be having problems.
I'll probably get flamed for saying this, but if this person were serious, I'm glad they didn't get into graduate school. If they're that depressed, grad school would likely only make things worse for them. To me, this underscores something I've believed for a long time. Guys, take care of yourselves BEFORE you apply.
