I’m a Type 1 diabetic (diagnosed in my 30s) and have been living with it for about a decade now. This really isn’t a “what if” situation. I know what will happen. I will die or hopefully just become incredibly ill.
It’s not really scary at all.
It’s just something I live with and prepare for as best I can. The one thing that I’ve learned from living with Type 1 is that all you can do is make the best decision you can in any given moment. My favorite doctor told me that diabetes is a disease that is all about making decisions. So is life, I guess.
