Obviously we cannot diagnose over the Internet BUT
If you are diabetic, your blood sugar is likely to be high, not low, so treating symptoms with sugary (non-)foods is no solution.
Do you know anyone with diabetes who could do a finger prick test? How about your local chemist? They could do a test, or introduce you to a patient who could help. They would of course have to get the other patient's agreement first. And I hope they would make you promise to see the Dr asap if the test is positive.
If you have got diabetes, the earliest possible diagnosis is desirable, as then you can be stabilised, & resume normal life in all departments, without worry. Uncontrolled diabetes is life-threatening.
Hope that helps.
