Half the academics I know have been on anti-depressants or in therapy at one time or another, including este servidor. The other half probably have too, but haven't told me about it yet. The manual of psychological disorders (DSM) contains some that are culturally specific. That is, they are disorders bound up in cultural definitions that are not recognized outside of that particular culture. This does not mean that they are not real. I would point out that all psychological disorders are culturally constructed. Why call "mal de ojo" culturally bound but not Western ailments like "nervous breakdowns"? The sufferer suffers the same ill effects whether there is a culturally specific name that has no purchase in other contexts.
Academics are knowledgeable about treatments and seek them out. They don't tend to see depression as a stigma, so they seek out help. What is stigmatized is happiness, satisfaction. You are supposed to whine and complain a lot, participate in the culture of "college misery." If you look too happy, as Z has pointed out, people will start wondering whether you are working hard enough.
Of course, I don't mean to say that people get depressed because of this culture, that they should just opt out of their personal depression by realizing that it is culturally constructed. That is easier said than done. Also, to say that something is constructed does not mean that it is not real. Also, to say that something is constructed does not mean that it is not real. Also, to say that something is constructed does not mean that it is not real. I cannot say that enough times. Our very reality is cultural, that is the air we breathe, our psychological reality.
I would also like to separate the genuine concerns afflicting academia from the cultural norm of misery. In other words, there are really serious problems that have to be worked on, since academia is under attack from right-wing politicians and corporate-minded administrators. We should put our efforts into constructive work to fight back. The cultural norm of depression is a more general malaise that is not particularly useful, since it make us not want to get out of bed in the morning. This malaise also makes us think our own work in not valuable, and hence makes us weaker in the fight against idiot politicians and administrators.
