Am i just sick or am i developing diabetes?

The symptoms of frequent urination, scant (small) amounts of urination, and headache all are signs of hyperglycemia (high blood sugar)-which is a condition that affects people with diabetes. It is interesting that you said you get severe migraines and feel sick after eating carbohydrates (such as white bread/white pasta) because that is one of the causes of hyperglycemia. I think you should call the doctor to get checked out, diabetes can get very serious very fast if you aren't aware of the symptoms of hyperglycemia (high blood sugar)/hypoglycemia (low blood sugar) and you aren't treating it. In the mean time try to avoid high sugar or high carbohydrate foods, having too many calories a day, strenuous physical activity as well as exercising less than usual. Also, the fact that it runs in your family makes it an even better reason to get checked out.
