Ugh! I'm so sorry your not feeling well. Remember we all get these
feelings and we hardly ever v*. You will probably be just fine.

Did you eat anything that disagreed with you or cuase you to start
panicking?
I did today...I drank too much soda and I have been feeling off all
evening. Blech

Just try to do something distracting or drink some tea and whatnot. It
will eventually pass...

I hope you feel better soon!!!
