Brittle diabetes

So I have been TD1 since 1986 (3 yrs old). My doctor diagnosed me with "brittle diabetes" at that time. I was later diagnosed that again in my early 20s. I know the term is antiquated now, but it is a real thing. My blood sugars have always been a roller coaster, no matter what.

My NP at the diabetes clinic I go too prints out my logs each time and literally gives me the 3rd degree. "Are you sure you are carb counting correctly"? Etc. Yes! I am sure. Then she tells me to try this and that, extending boluses etc. Each day it has a diff effect. It is so frustrating bc I do everything they tell me but I cannot keep my blood sugar level due to the form I have.

Does anyone else have this form of Type 1??
