To be fair, when I was diagnosed T1 (50 years ago) the diagnosis was death in 30 or 40 years (and the diagnosis now is just a few years off a non diabetic's lifespan if you take care). I would certainly prefer T1 to many many cancer diagnoses.... (I have a university contemporary in her late fifties with cancer who would love to have diabetes instead.)
The treatment for T1s has improved astronomically over the time I have been T1. (And, a bonus, when I saw my dietician two days ago for my annual T1 assessment she'd gone from "low carb is really bad" to "don't go too low carb".
