In 2007 Schwartz posted what was believed to be a suicide note after being fired from reddit: http://digitaljournal.com/article/341150
Being fired is also high on the depression list.
You're pointing out two dark moments in someones life. I've had far more than two and I don't by any means consider myself depressed.
That's actually the point... it is depression that kills, not merely subjecting someone to a "dark moment" in their life. We wouldn't have blamed Alexis and the rest of Team Reddit if Aaron had killed himself after being fired, we would have blamed his depression.
Seriously, please educate yourself before offering embarrassing opinions. Clinical depression does not mean automatic suicide, it just makes you more prone to considering suicide when things are bad.
