I Get Symptoms Like Diabetes, For Example, I Get Sweats,

I get symptoms like diabetes, for example, I get sweats, shake sometimes after a high carbohydrate meal (but not really that high, I just avoid carbs but when I have them, well I can get shaky), feel drifty almost like in a state of dream, after I get very tired and often have to lay down and I fall asleep. My eyesight also seems to often be on the blury side, even if eye test show my prescription is minima. In the last four or five years, every time I get a blood test, it comes back negative. When I had my eye exam a year ago the eye doctor said that I showed no signs but ofcourse it did not necessarily mean I do not have it. Yesterday my boyfriend who has diabetis test me when he was doing his, his came at 214, mine at 99, he said that is a good level, that was our fasting. Is there another condition which I should be concerned about or might be causing? both my grandmothers had diabetis and it runs in family (uncle, cousin, etc)
