How long does the average diabetes type 1 female live?

Hi I'm still a minor and I've had diabetes since I was about three and a half. I've been told the majority of my life that diabetes will take off 10 years no matter what you do, and it can take off up to 30 years or more if you don't have it in control. Going through puberty my blood sugar fluctuates a bit with my hormones, but generally speaking I have it pretty much under control. My average range is 70-150, like the standard diabetic's, but I aim for it to be more around 90-120. Occasionally there are higher and lower numbers, just like with all diabetics. I bike regularly (at least 30 mins a day, 5-6 days a week) as a form of excersize, but I'm still wondering if I'm more likely to die at age 71 or earlier as opposed to the average american's lifespan of 81 (for women). Medical journals and other legitimate sources are very much appreciated.
