Hey Steph,
Fortunately, it's very clear that you know what you need to do, because you're so able to admit to what you're not doing: testing your sugars, exercising, eating well.
These aren't supposed to be really, really easy things. They take commitment. You've gotta be willing to get out of bed early to fit in exercise or go to the gym after school when you're tired. You've gotta be willing to choose healthy food over ice cream more often than not.
And there is no way around testing your blood sugar: you are diabetic. YOU NEED to check your blood sugar. If that is an idea you're struggling with, then the biggest problem may be plain old denial.
Why do you not check your blood sugar? What is the most honest reason and answer to this question?
Once you can be honest with yourself about that, you can start changing your habits.
You have diabetes. I have diabetes. We need to check our blood sugars and take insulin for the rest of our lives IF we want to be healthy. THat's life. And I'd rather do it and live well, than waste any time waiting for it get easier!
It's hard for many of us:
"Let's Just Practice"
You gotta be willing to adapt!
Feel like you're the only one?
