Anxiety, depression, and PTSD may be adaptive responses to adversity: study
I'm most surprised to learn that this _isn't_ the current prevailing view in the medical profession. I am not a doctor, but it's always seemed more natural to me to view depression and anxiety as adaptive behaviours - albeit perhaps ones that can end up being triggered too far.I read an article once (wish I could find it) that one advantage of mild depression was as sort a "call for help and support" from other embers of a close-knit social group, although I'm not sure how well-founded the claim was.
