Cold, Flu, or Hypochondria?

Whatever I have it wasn't even possible for me to concentrate properly on a simple game of Candyland with my brothers. I'm pretty sure I'm not imagining the whole thing as my hypochondria usually doesn't make me feel like I've been run over by a truck. But I'm not sure about the severity of it. I figure it's either a bad cold or mild flu. Either way I hope it goes away soon and it isn't some brain-eating virus or I wasn't bitten by a black widow or rattle snake in my sleep (yup, that's the hypochondria kicking in.)
