Well I have both right now. I have a massive blood clot in my leg, that hasn't improved since August. I'm terrified they are going to put me in the hospital and I'm terrified of needles and such, so right now I'm not sure I would choose the physical over the mental health. Generally I would have agreed until it came to having a physical illness. You are right about it making it easier to explain absences, but the fear is terrible.
