first of all felt nice looking at your feelings towards your friend.
as one of the ans. explaining pathophysiology is anyways posted ; why don't you only become her counselor ?? !!!
Explain her ; make her comfortable to share her feelings. give her a confidence so that she can learn "living with diabetes"!
balanced diabetic diet will certainly help in avoiding sugar fluctuations and further complication. this may even lower the dose of insulin
So..... all the best.. to both of you !!
for any help / queries contact;
