I would start with your local team but try to see who is responsible for education in your NHS system as they would probably give you the most leverage......
I would also contact these folk......
https://www.diabetes.org.uk/
I would also think about writing a book about your experiences and emotions during it, along with the care points etc - one of the above should help you with the medical side.....if you need some help on writing, then let me know off line, Queenie... the thing being that a book can tie back to your presentations in schools, youth groups, and all the rest, could even be outfits like Rotary or the Lions that might back you for raising money for research etc......
This is very commendable and well done you for putting the idea forward.
