Hi Tosha, from what you're saying it might be low blood sugar but it could be other conditions as well. You need to see your doctor so they can run tests. There are several things to be concerned about like blood sugar levels, high or low blood pressure, pregnancy, migraines and so on. (In some countries, those symptoms could be malaria.) So, make sure you see your doctor as soon as possible and in the meantime, eat small quantities of food if you can keep it down (like chicken soup and crackers, tea) and don't drive! Hope you feel better.
