This article reads an awful lot like original research from the blogger, in the sense that it's baseless and not supported by anything other than the blogger's preconceptions and personal opinion.
This sort of nonsense is particularly dangerous as the blogger feels that they can prescribe cures for mental health issues.
Flagged.
I disagree with the article... when I (no work, no purpose) changed my diet, depression went away. Now I have work, no purpose and I can feel the pressure of burnout every time I'm stressed out... but I never got back to that low energy state of my depression..
