Does anyone have a reaction to sugary foods but does not test positive for diabetes?

[Dawn L]

After I consume a lot of sugary foods/carbohydrates I get really dibilitating symptoms. (I have already been tested for diabetes and it was negative.) I get red in the face, my eyes get glazy, I feel out of it, and my body feels like it is shaking inside but not outside. Then the surges come where my heart feels irregular and beating fast and I literally feel like I am wired but tired. I get extreme thirst and frequent urination. Then I am "done" all I want to do is sit/lay down but I feel like flight or fight mode. I also get a heaviness and burning in my legs, arms, icey cold hands, a cold numbness in my forehead chest and eye lids. I have severe insomnia and can only fall asleep with Ambien. I have brain fog and hot surges where my blood pressure doesn't change but my pulse races. Typically I run a real low pulse, 110/70 BP weight 135, 5'6" age 46 and done with menopause two years ago. Does anyone have any idea what might be going on with me?
