It can also be a personal failure regardless. People do have to assume some responsibility for their lives in the end. Besides near everybody has some personal tragedy or another or will inevitably have in the course of life). That doesn't mean it's fair, just that it's how it is. Even with a medical condition or actual trauma, you got to carry on, it's not like anybody else is gonna pick up the pieces for you.
We had a few dictatorships and several wars (including genocide and civil war) in the span of a century in these here parts (plus the usual personal stories that happen everywhere), and people moved on with their lives without complaining. I's a little insulting hearing people from cushy cities where nothing has happened lamenting about their "traumas" and "issues".
