> the whole antidepressant epidemic in the US (and other places, like Denmark, the self-reported happiest country on earth) is a symptom of a fundamental breakdown in the community aspects of society and a pervasive, deep-seated sense of mental rudderlessness infecting the more vulnerable parts of the population
That causes damage. Turning your ankle or pulling a muscle might be more obvious, because it's purely physical, but there isn't as much difference as you think.
There have been studies that show that long term unemployment causes permanent changes to a persons personality, one not easily healed by getting a new job[1]. These modifications to thinking and increased stress levels lead to physical changes (and argumentatively decay). Pointing out the source of the problem in society does not change the fact that it isn't mental illness. Quite on the contrary, giving a source is similar to pointing at a poisoned well and saying "That's why everyone is sick.", but then afterwards saying nobody is really sick because we all know the well is poisoned.
