The other thing to remember is to take all of the old data that's out there with a grain of salt. The old timers will tell you that things used to be very different. I know you already have some complications, but the fact is that, even if you found a 10 year old study that said that anyone who had complication X would have it progress to death/amputation/going to law school in 5 years, that's based on old data, using different techniques for glycemic control, and frankly, is mostly data from a period where the point was to keep you from going hypo, not to keep you in normal range. You look at the figures, they say people with diabetes die 10 years younger than average. My endo says normal life expectancy so long as you take care of yourself. So, be aware of the risks, take care of yourself, but you can't let diabetes control you.
Of course, we all have those bad, rainy days - literally and figuratively, as I look out my office window. It comes with the turf, and I don't think that's made clear enough to people at diagnosis. But look at it this way - my great-grandfather got into bed one day and didn't get out until he was dead of diabetes a few years later - pre-insulin days. We're the beneficiaries of a lot of new advances in medicine, and there's pretty much nothing we can't do - except fly a commercial airliner. (Oh well.)
Be concerned, be upset once in a while, but rejoice in life and in the opportunities we have as diabetics that people didn't have even 10 years ago!
