HI. You shouldn't feel nervous. It's up to the clinic to guide you on your insulin and if your HBa1C shows up too high then it will be up to the nurse/GP to guide you on some changes. If you have followed their guidance you have done nothing wrong. If the appointment isn't that helpful do come back and perhaps we can help a bit based on our own experience without conflicting with the clinic's advice. The clinic should be able to explain the ways to check that your Basal is right and also how to match the Bolus to your meals. I have had two lovely DNs and we just discuss options and share knowledge with a smile.
