Maybe your life is awesome, but people with chronic depression probably find it hard to just "look on the bright" there way out of it. Kudos to you for being the master of your destiny (honestly), but not everyone has it so easily.
Maybe it's their fault for not having the privilege to be exposed to the comments section of hacker news? :)
I am fully aware of the awfulness in the world. I know millions of people suffer immensely every day, and I want to do my part to alleviate as much suffering as I can. However, I also know that me being miserable will not help anyone. Finding joy wherever you can is simply the best response to a crazy, unjust, and often times cruel world.
As far as depression goes, I hope my comment didn't come across as dismissive of real depression. That is a serious condition that cannot be fixed just by sheer will. It can, however, be dealt with, and I have many family members who are living testimants to that fact. It must be treated like any other serious health issue; I am in no way advocating ignoring your problems, I am saying make the best of it as you deal with them.
