She is at a difficult age, even if she didn't have Diabetes. I sure feel for you. Maybe you can find someone that she will listen to at this time......most 15 year olds will listen to anyone except a parent.

There are teens on the forum, maybe you could get her to talk to them. In the meantime, here's a hug for you, I know you need it.
