Passed out during glucose test

Nina
So I am a nervous person I don't like doctors or needles. My 1 hour glucose test was at 9 am and my paperwork said to fast two hours prior. So I didn't eat breakfast and just drank the orange flavor. The nurse goes to draw my blood and she takes forever feeling around both of my arms for a vein. She finally  picks one and sticks me. As she's getting the sample I start feeling very dizzy and my vision starts to go black. I tell her I might pass out and then I don't remember anything until 3 nurses are surrounding me waving something under my nose. I thought maybe it was nerves and the anticipation. But I got my results back and my blood sugar level was only 59. No wonder I passed out...
