It sounds like anxiety...I don't see too many people on here saying they are sick, a few weeks back it was but now it is better. And to be the bearer of bad news people are always sick there is ALWAYS a sv* "going around". There is no time when it isn't in a city so to speak. It is bad right now because people are just over the holidays where they shared their germs and went out sick and didn't take good care of their hygiene and over indulged. So many people keep saying about noro outbreaks and personally it does irk me a bit but if it doens't come straight from the CDC themselves it isn't a outbreak it is a virus that multiple people have gotten. And if the media is talking about it, is simply because they are bored and need a space to fill so they dig and dig and dig! I think you are fine. Do you have any ginger or peppermint? Try to calm yourself, and put your mind in a different place rather then thinking strictly of a sv*...
