Hi Hollywood,
First off, i just want to say that if your daughter isn't ready to make the changes and be more active, eat more healthyfully, etc. then trying to push her won't help...but maybe if you can help educate her about how important exercise is when it comes to diabetes, she will realize on her own and want it for herself.
I just posted about ten links to diabetes & exercise & weight loss here:

I hope those are useful!
What do you think the hardest part about her diabetes is for her? You mentioned that she has struggled with it really every day -- is it the managing and balancing act or is it the emotional burden it lays on us? Or both?
Where she is at now doesn't mean she'll be in this attitude towards her diabetes forever! People can really turn their health around when they decide they want to. I think helping diabetics learn about what the disease can do to your body if it's poorly managed compared to what you're still capable of when you take care of yourself is a huge motivating factor for some!
