Hi
@Charlottelucy44
I have seen specialists (Diabetic nurse, dietician, Doctor) from the hospital recently and they didn't understand how frustrated I was because they couldn't answer all the questions I had, even though they were specialists. The thing I've realised, for my own situation, is that they can't tell me what to eat and when and they can't sort out a menu that would suit me (which I wish they could) as that is something I need learn for myself.
Regarding your insulin, is there a doctor at your surgery who is a specialist in diabetes? as it is your doctor who prescribes your insulin Your receptionist can answer that question. If there is, ask for a double appointment to speak to that doctor and explain your worries and concerns.
I hope this helps and let us know how you get on. Be kind to yourself regarding your diabetes. Once you have it under control, you control it. It doesn't control you.
