Hi Becky, welcome to the forum!🙂 There are many different types of diabetes, and not all doctors are aware of them or the differences between them. What is important is that the medication you are taking is helping to keep your blood sugar levels as stable as possible, and in 'normal' range.
The two main forms that most people have hard of are Type 1, which means your body has stopped producing its own insulin so you have to inject it, and Type 2 which may mean you are still producing insulin but your body needs medication to help it to process the glucose in your blood. Some Type 2s also need to inject insulin.
If you have any questions, please ask, there are lots of friendly people here that will do their best to help!🙂
