I worked with someone who committed suicide--not like, in the same office, but same company. It was a huge shock--she was a gorgeous, blond-haired young woman who just had this bubbly personality and a great position in the company. You'd think she was on top of the world! Nothing at all to be sad about. Never forgot that one. Didn't know her well personally, and was still in the Borg at the time. Just...shrugged it off, moved on, like a lot of people do at companies when that happens. But this question brought it back again. Particularly poignant because it could just as easily have been me, if I'd gone through with it the times I tried.
But it certainly makes me think, if there's a way to see that, you don't want to miss the warning signs. Having been in that suicidal headspace myself--even recently--I know what it's like to want to die, to want to give up. Not even sure what makes me keep going, but if there's something in there that does, I'd like to tear it out and give it to a poor soul that might be hanging on the edge as I was.
