I was once "friends" (in the friend-of-my-group-of-friends sense) with someone who semi-openly talked about their suicidal past. I engaged with them on the topic (only when they brought it up), no problem, never judged them for it, but they seemed (and still seem) to be in a better place at the time. We have since parted ways.

Another friend of mine recently had a nervous breakdown (and has since seemingly recovered). I doubt they've been diagnosed with depression, but their behavior makes me wonder -- ALWAYS happy/cheerful around others; not too successful socially, romantically, or physically; always willing to help (to their own detriment) but loathe to ask for help; and seemingly in a high-stress and low-human-interaction work environment. Seems ripe for the picking.

And then to top it all off, I'm playing Life is Strange, and completely failed to save the suicidal character. I'll leave it at that to avoid spoilers (it's a good game ;) ), but that part really opened my eyes to how absolutely screwed both I and they would be if I ran into a situation like that in real life. I mean, when it really mattered, even when the dialog options were laid out for me, I couldn't say the right things. How much worse might I make things when the dialog is on-the-spot free-flowing improv and there are real lives on the line? Fuck me...
