Welcome to the Forum!
First of all I commend you for seeking help, this is the first step. Please don't feel embarrassed to talk about your diabetes condition. We are all in this together. It appears that your average blood sugars are running around 350 mg/dl. I have a few questions for you:
How long has it been since you had your better control?
Do you have an active life style or do you play any sports?
Would you consider yourself over weight?
Do you count carbs and use this information to calculate your insulin for your bolus injection after meals?
Would you be interested in a forum, with other teenagers, to discuss your diabetes?
