IMHO, psychology is still waiting for its "germ theory" moment.
Not everyone, and it's reserved for long term untreatable severe depression, but it's important to note that it's very effective for some people.
1) There is hope! Don't give up.
2) Many people will not understand. That's okay.
3) Cognitive Behavioral Therapy (CBT) works. It's hard work, but it's easier than having depression and anxiety. It's really about renewing your mind. Best book on the subject is an old one: http://www.amazon.com/Feeling-Good-New-Mood-Therapy/dp/03808...
4) You have to find help from others. You will likely run into quacks, and well-meaning but unhelpful advisers. Don't give up.
Out of curiosity, who did you find that was able to help you?
CBT is however about fixing negative thought patterns. Start of chapter 3 of Feeling Good (I just pulled open the pdf) Burns says 'Illogical pessimistic attitudes play the central role in the development and continuation of all your symptoms'
I don't think I myself have posted about this before, and just did a search. Hacker news does seem to be often dismissive of the psych field though, as there is not a lot of good science that would appease a critical thinker.
But it doesn't matter what causes the emotions - CBT helps people deal with negative emotion no matter how they're caused. Pain management in cancer patients is a good example where emotions are caused by something external but where CBT is still effective.
You might want to have a look through some better books or websites to get an idea of what modern CBT involves.
What needs to be mentioned is that the author despite his professed history of severe clinical depression, is a published author of somewhat notability, whose last book was vouched by James Wood, the literary critic of New Yorker. And despite whatever professed outward collective-mentality present in IT, I know that many of my friends and co-workers suffer from existential doubts, personal isolation and obsessive-compulsive behaviors in private, if not more so. If anything, the fact that the author chooses to share his personal history so openly makes me more comfortable about his handling of personal issues than others who lead double of lives and "#winning on facebook" and "suffering alone."
As another perspective on depression and anxiety counter to the HN's mainstream answer, I highly recommend "Happiness and Its Discontent" essay here (http://chronicle.com/article/HappinessIts-Discontents/144019...)
"But we are mistaken when we interpret anxiety and other forms of existential disorientation as being at odds with a well-lived life. It may well be that they are an essential part of such a life."
If existential anxiety is part of a well-lived life, then by definition, why does everyone seem to prefer not to have existential anxiety?
