Not to detract from all the valid points raised in this thread, but the elephant in the room is that an individual’s level of education is generally associated with increased intelligence, and higher intelligence is associated with much higher rates of almost all psych diagnoses.

The same is also true in most other areas of higher personal achievement: lawyers, CEOs, politicians, etc are all disproportionately on various spectrums of depression, substance abuse, sociopathy, narcissism, and so forth.

At least part of the problem is how we view mental conditions as a society, which leads people to think that this is abnormal.
