Yes, I have been there myself, so can empathise! I guess all you can do is encourage ger, without nagging her to do the tests, and to try and manage her condition as best she can. It is difficult though, you clearly mean well, and I am sure you will be understanding, but it does sometimes dound like nagging! Encourage her to join the forum?
What absolutely made my mind up to improve my diabetes care was the realisation that diabetes did not mean that I couldn't have children, but it did mean that I had to be really take care of myself. This may not be your plan at the moment, but I mention it as I had always assumed, that as a diabetic since early childhood, and with a not too good track record, I would not be able to have kids,,,discovering that I could, and it was something that WAS within my control gave me somethingto aim for. Diabetes, especially in children does lead youto fell that it "isn't fair, and why me?" and it seems beyond your control. IGettingthe condition is beyond her control, but how she lives with it something only she can lok after, If she makes that choice, she has everything to live for.
I now have 2 children, who spur me on to look after myself everyday. It is hard work, and you mustunderstand that, but so, so worth it.
