Dear adrianne75629,
I can assure you that what you are experiencing is NOT hypoglycemia.
A non-diabetic's fasting (after not eating or drinking overnight) blood glucose level should be between 3.9 and 5.5 mmol/l (millimoles per litre) (that's 70 and 99 mg/dL (milligrams per deciLiter) [that's for those using the American Standard for blood glucose measurement], though some laboratories now accept 3.6 mmol/l [65 mg/dL] as being the acceptable lower limit.
People who feel symptoms of hypoglycaemia at such high levels are normally those that are diabetic who's blood glucose (sugar) level has been running high for an extended period of time OR those that are truly hypoglycaemic. Even then, none of your readings ... or the readings that you've given here ... are within the realms of hypoglycaemia.
If your doctor were to look at you as though you are "an idiot", you seriously need to find another doctor. NO doctor should ever consider their patient's symptoms reflecting on their cognitive (thought processing) abilities.
Youi SHOULD tell your doctor the symptoms that you're experiencing as s/he MAY well send you off for an oral glucose tolerance test (OGTT). This will determine whether or not you are having true hypoglycaemic episodes. If it does turn out that you are hypoglycaemic, you MAY be required to undergo further testing in order to determine which type of hypoglycaemia it is that you have.
The most common type of hypoglycaemia is called Reactive Hypoglycaemia, which occurs when the pancreas overproduces insulin in response to food and/or drink intake. It's this type of hypoglycaemia that is treated by you breaking down your food intake to smaller, but more frequent meals throughout the day ... usually 5 or 6 smaller meals that contain fewer carbohydrates, but also include a greater proportion of fat or protein. (Fats and proteins slow down the absorption of glucose, which we get from the breakdown of carbohydrates during the digestive process, which, in theory, should prevent the hypoglycaemic episodes from occurring.)
A much rarer type of hypoglycaemia is called fasting hypoglycaemia. This type is normally due to an insulin-producing tumour which MAY require surgery to put right.
I wish you well when you meet up with your internist in a few weeks time.
Mick
