Welcome to the Forum!
Type wise, given you are insulin dependent, I would think that you are classified as
Type 1.5, which basically means you are a later bloomer and didn't get this as a juvenile. However, you could be classified as Insulin Dependent Type 2, as well.
I am sorry that you are have all this trouble. Hopefully, your doctor will get your meds figured out.
Read through the first three threads in the Type 2 Section, when you get a chance, if you have not already done so. These threads will most-likely help you a lot, even though you are insulin dependent, the information is good for everyone. Self education is one of the keys to successful management of your diabetes, along with a healthy / sensible diet and exercise. Basically, diabetes requires a life-style change for the better. Good luck with your control and management.
