I have to say, I was diagnosed T1 as an adult (30) and I am very grateful it came at a time where I felt prepared to handle it. As they say growing up is hard enough. At least I never had to deal with going to the nurses' office for a shot, never had to deal with the reaction of other kids, drank without worries in college....you get the point. Now that I have kids, I can't imagine having to put them through what I have to go through, at least at their ages, and I pray I never do.
I am grateful that I was diagnosed when I was an adult, and in the era I was. When I first started I had to take NPH (which was awful, at least for me), but soon Lantus came out and then the others. I have never known diabetic life without the luxury of glucose meters, intensive management, designer insulins and food labels! Had I been diagnosed as a kid in the 1970's, I would have had to learn to survive without these things.
It's a bummer to get the D anytime, at any age. But, I am grateful for all of my non-diabetic years, and also for being in diabtetic in 2012 not 1962.
