I Hate It When I Am Sick

I feel so tired and weak when I got home from work. I do not understand why. All I know is that my lunch was great and it is not so busy at work. Once in a while I feel hungry but I brought snacks with me, and ate them when hunger strikes. A slight headache is trying to get in the scene. I can feel the pressure in my sinus. No! I don't want this. I do not want to call in sick tomorrow. Because I hate it when I am sick.
