In my case

I have been quite ill with stress. No, I'm not sitting at home wringing my hands and worrying about things. Let me tell you what happens. To begin with my belly slows down over a period of weeks, and reaches a point where it becomes quite uncomfortable. When that happens I then get a dose of thrush. Glad it ain't toucans. As that starts to clear up I start burning up with a fever that won't break. I can't sweat to start with, so have headaches and painful joints both day and night. Last night was awful. I think I was delirious. I kept waking up hurting, and full of old music hall songs. It's unspeakably horrible. The good news is that I've finally had my first sweat, so I know I'm on the mend. You will probably understand now why I have remained in bed since last Thursday, and how strong I have been in making sure my obligations are fulfilled.
