As a type 1 diabetic, here in the UK and many other parts of the world, it has become a legal requirement to inform the driving licence authority that you are Type 1. Usually a doctors report is required to back up your claim to be able to drive SAFELY in that you have maintained GOOD stable control of your diabetes and haven't gone Hypo within a certain number of weeks.
You need to get DVLA approval here in the UK, not only to legally allow you to drive on our roads, but also you will need to get approval from your vehicle insurer. This is most important as so many insurer's will look at any loophole should you be unfortunate and need to make a claim in the future.
As for getting along with your diabetic team, well in that respect you aren't alone, but changing to another team isn't easily done and sometimes as hard as it is, it becomes easier just to simply agree with them, nod your head at the appropriate time, smile when necessary at them, and do your own thing in the background which you seem to be doing already and which is giving you such good blood glucose control and day to day management.
I'm sorry to say that I don't think there is any alternative as I can readily confirm from my own experience and swimming against the tide will not give you the result that you are hopefully seeking.
