Hi
@Disbelief1959 , welcome. You will NOT look like a fool in this forum.
Every one of us has had the abrupt introduction to being diabetic. And I suspect very few of us have had the advantage of having a close family member with personal experience of managing diabetes or bang up to date knowledge in the meds and techniques available today. We all know that diabetes can be complicated, confusing and contradictory. On this forum there is invariably someone who has encountered a problem that someone else is asking about. So don't feel inhibited - dive in if something is bothering you.
I'm delighted for you that your diabetic nurse is hospital based, it is highly likely that she will be what we describe as a DSN (Diabetes Specialist Nurse). Sometimes in GP surgeries there is a Practice Nurse assigned to helping with the management of those patients in the Practice with diabetes and they don't always have the expertise in unusual forms of diabetes. That's you - a T2 started on insulin straightaway.
I'm backing out now, I know very little about T2 and still learning about the intracies of taking insulin! But again, welcome.
