Hi Ashwee, what a pretty girl you are, assuming that is you in your picture. You will not be the only teen who gets burnout and can't be ***** to self care. In fact many diabetics simply decide to stop insulin, eat everything they really should not be eating, ON PURPOSE.
Some do it to lose weight, some to fit in with their peers. Many feel "safer" running a bit higher, as most of us know how nasty you feel before, during and after a hypo, right?
I am not even close to your age, but things I have done in the name of hating diabetes would have you checking your pockets for the key to the padded cell. I am not a born again Diabetic, neither am I judgemental, so maybe if you are willing to share with the great folks here some more details of your issues, I have no doubt something can be sorted
