I have been feeling like everyone has it too!! Everyone on Facebook seems to be posting about it but it is true that we just got over the holidays and things go around like crazy then. If your stomach is upset, drink some ginger ale. Try to do something to take your mind off of it if you can...read a book or put on a really good movie you love. I know it is incredibly hard to get over anxiety attacks. I feel so for you right now and I have been in your place as I'm sure we all have.
If you're worried you're getting sick try taking garlic pills, oregano or colloidal silver. These can be found at pharmacies, GNC or other health food stores. All three of these supplements will not hurt you and will aid your immune system with fighting off nasty things.
I hate winter!! Do you live in a cold climate or warm area? I am always curious how viruses are carried in different areas. I live in New England so the winter is the worst for illnesses.
