Poorly

I would like to know whether I am a hypochondriac or not. I've been off for most of last week with no real signs of illness other than feeling crappy and needing to sleep. A lot. Generally, unless I am showing visible signs of being ill; fever, vomiting, the runs etc, I will feel guilty about being ill. I will also try to go back to work way before I am feeling better and end up getting sent home in disgrace. This time I cried which was so embarrassing. I would just like to know whether my brain is in control of my being ill or whether it's the bits of my body that are affected by the actual illness. I think mainly, that I would like to stop feeling guilty about being poorly.
