Here's some advice: Stop looking for advice. I don't mean to sound harsh. But considering that you had to ask your psychiatrist whether or not you were depressed (not to mention that you accepted his/her answer unquestioningly), and considering that you are asking the strangers of HN what to do, I would suggest that you aren't really in touch with your own mind and actions.

Advice will be helpful. But in the end, the only one who can leave your job is you. It sounds like you need to do it, so just do it. You'd be surprised how well you can think for yourself once you make yourself do it. :)
