Survival instincts are strong tho, suicide would be a lot more prevalent in war zones and heavily impoverished regions if the will to live didn't most often prevail on terrible living situations. As horrifying as the thought of a nuclear collapse of civilization would be, I'm sure there would be something worth living for on the other side - assuming you're somewhere that remains remotely livable and don't die a week later from body melting radiation poisoning or from famine within two months... which I guess is likely in most places, maybe it's my non-urban Canadian bias and irrational optimism (I'm doubtful this scenario equates a carpet-atomic-bombing of Earth's surface) speaking.
