You make some fair points, but suicide is hardly an epidemic of youth. White, middle aged men account for around 70% of suicides in US each year. Perhaps most of these have no family to turn to or have already seen theirs destroyed.Although this research isn't sure quite why, it could also be linked to the reason why suicide rates are much lower in adulthood. If you've already made it through the worse, then there's really not much the world can throw at you.
