Yes, you can certainly get some acknowledgement of this from me, having lived it and researched it for many years (and also having succeeded in overcoming it by accepting this position).

Sure the propensity to feel depressed in response to a given experience may differ from person to person, but it is a product of evolution, and is far too common to be pathologised as a "disorder".

We have this assumption that a materially privileged life in a rich society should entitle us to a life of happiness, and any divergence from that is an "illness".

This ignores the fact that there is much that is unhealthy about modern western society, and the proliferation of depression among seemingly well-off people in rich societies is a natural reaction to that.
