Mental Health Days

At some point over the next few hours, I'm going to develop a life-threatening illness. It will be directly related to the fact that tomorrow is the only day of the week in which I have no prep time and when I DO have a lunch duty. I'm thinking of a good name for this mysterious illness, which comes and goes at will (mine) and rarely lasts more than one day. It never seems to hit on weekends, but nine times out of ten will come on either a Monday or a Friday. Post-grade 7 stress disorder, perhaps? Any suggestions? (I'll be home all day tomorrow to answer them!)
