Why do I feel so embarrassed admitting I have Type 2 Diabetes?

I was diagnosed with Type 2 Diabetes last fall with an A1c of 6.7. Since then I have worn a CGM and managed to drop my A1c to 5.7! At first I had a nice Dexcom G7 but my insurance refused to cover it due to not being on insulin and no history of hypoglycemia (I do get hypoglycemic but no recorded history). Then I used the Dexcom Stelo which is over the counter but a bit expensive. Finally saw an endocrinologist and got put on the Abbott Freestyle Libre 3 Plus which I self pay but found a coupon so it is cheaper than why I paid for the Dexcom even with insurance. Anyway using the CGM I have lowered my A1c from 6.7 to 5.7! I just don’t understand why insurance won’t cover a CGM for Type 2 diabetes when it is so helpful in knowing how foods affect your blood sugars. I also know I get hypoglycemic at night while sleeping and when exercising but a slice of bread will bring my blood sugar over 250. I am so excited about the progress I have made mostly from wearing the CGM and want to share about it but am to embarrassed to admit to family and friends that I have Type 2 diabetes because they think it is caused by being lazy and poor eating. Why can’t people understand it is a metabolic disorder and there is so much more contributing to it than just eating too much sugar. Even in my skinny 30s I had metabolic syndrome with high cholesterol and a high fasting insulin regardless of being active and reasonably fit. I want to talk about having Type 2 but there is such a stigma attached to it even in the medical field. Sometimes I feel like the doctors just shake their heads. I wonder first how many others feel this way and how can we change the way Type 2 diabetes is regarded by others?
