Not to seem overly negative. Not to suggest that people who do see D as a blessing in disguise are wrong.
Personally though, no.
I like the life I'm leading. Plenty of wonderful experiences and plenty to be thankful for. At this point, my life has taken a path that I would not choose to have changed. There is too much that is precious to me.
Still, for me, thanking diabetes for any of that is a bit extreme.I want to be rid of it and I would not miss a damn thing about it if I woke up without it tomorrow morning. Since that will not happen, I will continue to do what I have to do. Diabetes hasn't given me anything worth mentioning but it can take everything I've gotten, despite having it, away from me if I let it.
