diabetes symptoms but negative

I have been feeling this for almost half a year, and i still can't get a diagnose of what's wrong with my body.  I have tired, fatigued and weak all the time, and feel like i need to eat, and if i dont eat i feel sick (weak, fatigue) and feel like i will faint if i dont eat or drink something. And my body feels werid all the time.  I've seen endocrolgist, and he suggested i check my blood sugar everytime i feel sick, but my blood sugar is normal everytime i check. I have gain at least 10lbs, and i just feel like i need to eat and drink constantly. Before, i could go on a day without eating for a long time, now i need to eat every 3-4 hrs. I had blood test for everything, and even did a CT scan on pelvic and abdominal, and still can't get a disgnoise. CT reveal a bit liver fat, but doc says its not enough to make me tired. 

Does anybody have similar symptoms like me? I dont even know what doctor to see anymore.
