Is it frustrating when people should know better...but seem to have no clue?

I was hospitalized last week,for the second time in a year, with low blood sugar

I have learned that carb, such as breads, are a way to gradually raise your blood sugar which is good.
Also proteins are important. If I eat something that’s pure sugar like cakes or candy (it’s Halloween damn it!) it causes your blood sugar to spike and then just as suddenly to crash. This is bad. To counter act the crash you eat some protein…even a spoonfull of peanut butter.
So I got that.
Well I bought some Eggos, which I love. But that,with syrup, is a lot of carbs!! Simple,fast and BANG!! Bad.
So I was wondering what easy and quick protein I could counter that with. Someone mentioned protein shakes and that seemed perfect.
However since this.is uncharted territory I’m double checking every step so I called my doc’s nurse line.
She obviously hadn’t checked my chart and treated me as if I was some regular, probably overweight person trying to lose weight she said, “We’ll just don’t eat that food with lots of sugar and butter!” (I’m 20 pounds under weight. Butter is good. But that’s a different story.)
She said that and I said “But I tend to low blood sugar!” There was a pause which told me instantly she hasn’t reviewed my chart.
Then she lamely said “Well just stay completely away from that sugar and butter stuff.” WTF?
