Hello~It sounds to me like you are coming down with the flu alright. I would go to bed, start drinking plenty of fluids, mainly water or fresh fruit juices, and if you can, have a friend get you some Vitamin D3, C, A and vitamin B at the local health food store. If it gets worse, go to the ER for a shot or a test to see if it is indeed the flu or some other "bug"
I hope you feel better soon.
