You really need to see a doctor ASAP for analysis and treatment of your nausea, lack of energy, and dizziness.  There's more going on with you than a "possible" association with diabetes. If the doctor finds you have diabetes, he/she will educate you on proper nutrition and exercise along with starting you on medication to help control your blood sugar. Make an appointment today.
