Mr. Neideffer, my Algebra II teacher, tapped his knuckles loudly on the board. He looked at me expectantly, prompting me with more loud taps against the blackboard, “Well, Rhonda, what’s the answer?”

Rhonda is my mom’s name, and some 25 years ago, Mr. Neideffer had my mother as a student in Algebra II. He called me Rhonda so often that I eventually stopped correcting him and just answered to my mother’s name.

On this day, we were studying direct and inverse proportions, and while I didn’t know the answer to his question, the irony of the lesson was not lost on me. Instead of focusing on Mr. Neideffer’s question, I thought about the age difference between my mother and me. When I turned 25, my mom would be 50, and I would have been alive half as long as she had been. When I turned 50, my mom would be 75, and I would have been alive three-fourths of the time as she had been. We would always be 25 years apart, but as we got older (an increase) the difference between how long we’d lived on the earth would decrease.

In the diabetes community, people often celebrate their diaversary (diagnosis + anniversary). While we talk about it, we don’t celebrate it yet, as we’re waiting to see how Henry wants to mark this day.

Since the invention of insulin, every diaversay is no doubt a marvel; however, I can’t help but feel somewhat sad because it marks another year of living with a chronic disease, which is hard work that we do everyday. Yet, another date makes me sadder: December 15, 2016.

This day marks the midpoint, where Henry’s lived as many days with diabetes as without. Everyday after December 15th is an inverse proportion: the amount of time he didn’t have diabetes decreases compared to the time he will have it.

Not uncommonly, someone will tell me that we’re lucky Henry got type 1 diabetes so young because he won’t know a different life. While I want to believe this, I can’t. I think of the greater proportion of time his blood vessels will be exposed to high blood sugars, the greater likelihood of complications. If I got diabetes right now, I’d be in my 70s before I’d have lived half my life with T1D. Henry turned 6 this year.

When I become too forlorn about the burden of type 1, and what that means for my son, I remind myself that the miracle is he turned 6—that 96 years ago, before insulin, people with type 1 could expect to live 2-3 years after diagnosis. The miracle is everyday after January 11, 1922 when insulin was first delivered to a person with T1D, and that miracle includes today and the one after.
