It's definitely a little weird. Just about thing first thing you realize (or should), is that sugar=carbs. You also know, and are told repeatedly, what to avoid (and thus what to go for in the case of an emergency). The nurses/doctors always told us that the expensive shit wasn't necessary. The glucagon shot is expensive, and only is really needed if you're unconscious, which makes it sort of useless to carry because the people around you who know you're diabetic are (I guess maybe not...) usually informed enough to shove something like orange juice or soda at you, well before you go unconscious. You (or the parent) keep something like soda, cake frosting / honey, or candy bars in proximity. Heck, I use granola bars because those little shits will spike the blood sugar faster than a candy bar, and they don't melt. My car has them, my backpack has them; I once carried the little juicy juice boxes but those spoil faster in heat/cold/physical bruising cycles of being carried around.

Even in just the context of day-to-day life, I know to control the blood sugar by what I eat. If I'm going low, I can have a very small amount of those no-no items, like soda or a candy bar. I also know that if I consume that, the blood sugar will spike before the insulin kicks in (it's really hard to give the insulin ahead enough of time to stop the spike without also driving the blood sugar low first). It's why they're avoided in the first place. That makes the poor girl's lack of awareness of it sound really, really odd.

It sucks that she felt embarrassed about it. I get tired of the comments/thoughts that behaviors are diabetes-driven from people who know me, so I get it. It can be quite the source of amusement though. There are stories in my family of the ones with diabetes doing some crazy things, and I've got a few of my own that I joke about. Waking up with a low blood sugar makes me think the dreams were real, as an example. Sure, everyone's got some sleep paralysis thoughts, but try huddling under your covers for an entire morning thinking you're about to get busted by cops for murdering abe lincoln.
