Answers: I recommend seeing your doctor. Sounds like hypoglycemia( low blood sugar). The doctor will get something done blood tests to determine what is wrong.
In the mean time, convey candy or crackers and when you start feeling lightheaded, eat a piece and see if you perceive better. Stand up slowly so you don't pass out.
Good luck and I hope nothing serious is wrong beside you..
