Unwanted pain

On Saturday, I did not go to London (to the annual event in the embassy) because I was weak. I thought it is just work, but also knew how being weak in the crowded tube has previosly ended, I did not go. Also, I had a friend in the hospital, so better to visit her. On Sunday, I could not visit her, because I thought my weakness is more like illness. In the evening I was playing the flute and all the time I was actually not playing, had the outside jacket on, as it was cold. S also thought it was cold. Finished and ran home (because I was so cold). Monday, normal work day, pretending I was not weak or ill or anything. The fever hit at night. In the morning, I still kept pretending everything was fine, despite having no voice ("Yes I am going to work"), until I realised I cannot actually get up because I feel so dizzy. So, no going to uni, but I can still do computer work, right? It went very slowly. In addition to temperature and no voice, I had the worst muscle pain. First I thought it is from some exercise....wait, I haven't done any! It got worse and worse. Second day, third day....now I think I am recovering and just suffering from some a bit uncomfortable and painful cough. Yesterday I had some food too, some light fish and vegetable hot-pot. What a shame, beautiful autumn and I am weak! And I have wasted a week.
