To quote a smart person I know: “Yeah, sure, you could give up, but then who’s gonna feed the kids?”
When your life is hand to mouth, there’s not a lot of room left for suicidal stuff. Too busy surviving. Especially if there’s people depending on you.
Even if you’re suicidal, you don’t have the luxury to go through with it. And even if you’re depressed, you don’t have the luxury to give into it. Because if you do, then you don’t eat and neither do yiur kids. No choice but to keep going.
Life’s fun like that.
