I'm type 1 and on insulin. A great place to go for information and support is the website for the American Diabetes Association, that's how I found my endocrinologist. Diabetes is nothing to be afraid of. Most important is to find an endocrinologist you're comfortable with and can talk to.
A lot has changed regarding treatment. My insulin dose is based on carbohydrates. Ask your doctor for a good nutritionist for help with a workable meal plan, something you can live with and works into your lifestyle. And don't be afraid to ask questions.
There's a lot to learn about diabetes, I have a much easier time than my grandparents did with it. If you're feeling overwhelmed by it right now, that's okay - it goes with the territory.
Please, pm me anytime if you need some support or if there's anything I can do to help you out or if you just need to vent. I'm solidly on your side.
