Similar story , diagnosed in the middle of covid with type 2 Blood sugar was in the high 20s, diabetic nurse blamed me, my life style, not eating regular ,weight ,long work days, lack of sleep, ect.
Last year i changed doctors as i was so ill and no matter what i did the blood sugar was up and down. I was sick of her making me out to be a liar on what it eaten or done to change things. Id lost over 4 stone in weight and and was in so much pain.
The new doctors only had me on their books for only a month. Id had ECGs even an Endoscopy. They then said they would like to do a c peptide test.
This took a month to return and with in 2 days i was under the Diabetes team at the hospital with two lots of insulin a CGM more leaflets than i could carry all this at 57 year old. sharp learning curve to say the least.
