The author isn't talking about you.
The author is talking about the people who will inevitably email with explanations about how she's doing something wrong or things are not as bad as they seem or any number of other options.
I have asthma in a particular form, and when people hear that I get triggered by extensive exercise and hill climbs and that I have to take things slow (it's gotten progressively worse in the last two years after COVID) I will inevitably be told "well you need to exercise more."
Exercise can't fix scar tissue, bob.
Because that's what I'm fighting. I don't have a full pair of adult lungs. I have two lungs that got the shit beaten out of them when I was 3. Could I use some more exercise? Certainly. Will it magically fix my asthma? no.
Sounds familiar. I was often told "just use your inhaler, you'll be fine!". How I wish it were that simple.
Sounds like the author is talking exactly about them, a diabetic who could offer some useful feedback.
And sure, I guess you can wish painful death on anyone who shares your form of asthma and has suggestions, but it definitely says a lot more about you than them.
Many people ignore that there is a good chance they will end their life infirm or disabled and are therefore happy to shit on people with chronic (or even acute!) diseases and disabilities like that's a group of aliens that they will never belong to.
No worries though. As we say in Greek, "όλα εδώ πληρώνονται". Loosely translated, what goes around, comes around.
