What is the difference between being chronically unhappy and being chronically depressed?
I watched that "1 Psychiatrist & 20 Depressed People" Jubilee video today, and Dr K mentioned an example of a patient to whom he once said "I don't think you have depression, I think you are just unhappy". What exactly is the difference here? I get that you can be depressed for no reason - you can want to die in spite of having an outwardly good life. The depression itself might be your only complaint in the most extreme cases.
What if you feel like life is a miserable experience because of a lot of specific but unchangeable reasons that you find hard to stomach in various ways? Is that being unhappy or is that being depressed? How bad does the world need to get, before we would "grant" someone that it's just totally the reasonable reaction to no longer want to partake in life itself?
And how would unhappiness be treated differently from depression when you can not change the circumstances that make you unhappy? Do we just not have a medical treatment for that because it's not rooted in malfunctioning biology, and instead is caused by correctly functioning biology trapped in a bad situation?
