Oh, jeez
Sorry to hear... I can't imagine how difficult that was to write, but I hope it helped a little to get it all out there, and I hope some comfort is felt by all the obviously caring people in this thread.
My cousin was also diagnosed with Juvenile Type 1 Diabetes at age 16 and is now 46, living a perfectly healthy life with a 10 year old daughter and husband (in Calgary). It will take a while for your daughter to adapt, but the technology available these days should hopefully make it easier for her.
All the best to you and your family, huge hugs and much strength.
P.S. This community is pretty awesome. The responses you've gotten have really been heartwarming. Take care, and GO FLAMES!
