I'm sorry but this is just crazy talk, no pun intended. My depression has hurt me in so many ways even if I'm 'over' it. It hasn't made me this world-weary stoic, it has hurt my ability to be an effective person, relate with others, socialize, be optimistic, etc. There's no silver lining to it. I think a lot of these extremist opinions are very dangerous and on the level of anti-vax stuff because they can cause death. 2% to 9% of people that have been diagnosed with depression in their lifetime will go on to complete suicide. These are non-trivial numbers.
