Negativity in the profession is a funny thing. What I mean is that a full professor at an Ivy-equivalent place with a six-figure salary can be as negative as an adjunct on the poverty line. I don't question anyone's experience. In other words, if that relatively fortunate person is in a professionally abusive situation, then I won't say that they shouldn't feel the way they do.
Negativity can be a cultural norm too. We're always supposed to say "this time in the semester is brutal" and agree with each other that way in the hallway. I never just say: "Are you kidding me? They pay me to read poetry and chat about it to nice young people."
I tend to attribute my problems to myself, so I never said my depression and anxiety, quite heavy from about 98-05, was the fault of the profession or of academia, or of my department or institution. Maybe I should have, but I didn't.
