Hi Jessica - While a T1D diagnosis is most likely to occur between the ages of 10 and 14, there are plenty of people like you. I was diagnosed at the age of 30. I was diagnosed in January, way back when, and I remember losing weight through the Christmas holidays while still enjoying all the holiday food treats. It was my eyesight going blurry that sent me to the doctor. Before that I had the classic frequent urination and a thirst that wouldn't stop.
I've also found diabetes socially isolating. If you don't have it, it's hard to "get it" and really understand what we are up against. I've made peace with that idea. Nobody can really know what's going on in another person's spirit. Just as I can not, for instance, identify with what someone is going through that just received an Alzheimer's diagnosis.
But I have found a few non-diabetic people with abundant empathy that seem to glimpse the difficulties that we T1's face every day, every meal. That, combined with trying to connect with other T1's, has helped me to positively shape my perspective.
Attitude is important but for me, but the persistent quest for knowledge about T1 diabetes research and treatments is the thing that keeps me going. The old adage, "Keep your friends close and your enemies closer," applies well to my relationship with T1D. Diabetes is my mortal enemy and I want to know everything possible about ways to tame it. It's a wild thing that will never be dominated until and if there's a cure.
Good luck to you!
