Interesting idea for sure. I don't think it's that's simple, maybe for some people but not me. My depression is about looking at real things in ways that are not real. I have to constantly snap out of it and realize things in my life are good and the way I choose them to be, and the way I want them to be. My issue is idealizing certain things in an unreal way, causing me to have longing and sadness. That triggers my depression. This would actually reverse the whole idea for me. Obviously my depression is just a symptom of other, bigger issues. Guess that's what I get for being an INFJ.
