Attention Nurses/Dr./PA can someone help me?

im afraid i might be hypoglycemic. I have not been diagnosed yet though. and im thinking what if when i go see my dr. my sugar levels are normal however sometimes if i go too long without eating i experience symptoms of hypoglycemia and it goes away after i eat. My Dr. appointment is next week at 4pm. i told them by phone that I want to get checked for hypoglycemia. How should I prepare?
