Bummer. :/ Well, have some hot tea with honey, take your vitamins and cold-medicine. I also find echinacea (a herbal supplement) can help in fighting off and recovering from a cold/flu. Of course see the doctor if you haven't already (or if you think it's getting worse). And, this is the hard one, get some much needed rest (sometimes we push ourselves too hard, I know I do when I'm focused and "in the zone" of a project). Get better soon, and good luck.
