It's not fun and im not T1, I am insulin resistant, insulin dependent T2, which i keep controlled with a low cal/low ish carb diet and a fuck ton of insulin.
I tried keeping it controlled with low carb/keto/low cal, but that a/ didn't work b/ is a major risk factor for my heart problems and also my inoperable gallstones... so after a year of refusing insulin, gave in..
I've just added Ozempic today, so that will be weeks of feeling sick as well as the very limited boring diet, and weight-gain amounts of insulin if I even look at 'normal' (meat n two veg' type foods.
The fear of hypos in your sleep, or hypos in my case where im NOT in control of where I go (I am also disabled, I am reliant on whoever is with me in many cases to fetch something, act fast etc. Two of my family members think they can just leave me having a hypo, or going hyper, and not pass my kit, not fetch something to eat etc etc, so now I can't go anywhere with just them as they'll just kill me!).
Worrying if ill lose the use of my feet entirely, will I go blind, is my nerve damage diabetes related (no, apparently, it is compression in the spine, but the diabetes means im less likely to get that treated!)...
Just the miserable relentless day in, day out, FOREVER aspect of chronic, lifelong illness, there are no days off from it.
T1 I think 'looks' like it might be fairly easy to deal with, from an outsider perspective - because they're not privy to all the thinking that has to go on, all the worrying, all the what ifs and the control that needs to be had. Compared to a health condition that requires a wheelchair or some other obvious visual aid or difficulty, it probably looks pretty 'easy'... but as with maaaaaaaany things, outsiders, those who do not experience these things themselves, will always have a much more simplistic view of things!
