I'm worried about Hannah

OK so I'm starting to really worry about Hannah and it is affecting my personality. Her glucose is running extremely high and we have her under our thumb getting insulin in her. She woke up with it over 300 this morning. We have only had one reading below 300 in the last 4 days a couple over 600 and several between 300-600. What the hell is going on? It has always been a struggle getting her to take her insulin but the glucose never got this out of control. Makes me wonder if something else is going on. I am so stressed about this and what Best Buy did to my checking account that I want to scream. I really want to curl up in a fetal position and sleep for a month. Oh well, can't do that, drinking won't help, I don't smoke or do drugs so I guess I will pray.
