It's hard to decide if you want to list mental health issues when dealing with a non mental health situation. Does depression really matter if you have a broken leg, probally not, but then it might or might not if you were going in for an ulcer. Depression causing stress, leading to the ulcer, or maybe there is no connection, would be sort of a case by case sort of thing.

I used to put my depression down on everything but now I'm seeing that as a bit of a mistake, medical records are not nearly as private as you might think, so these days unless they specifically ask about mental health I don't put anything down.
