that's not it, it's hard to imagine when someone is depressed to that level, nobody is aware, not his close friends we clueless, I'm not sure about family.
It came so out of the blue. the fact he is healthy and has everything is something to live for.
His life didn;t have to end, it is hard to believe. He looked fit, active and healthy.
I know mental health can be a demon but to be depressed to that level you think someone would have noticed and helped earlier.
