I don't want to disparage your nurse WM (who may be brilliant) but as far as I am aware a practice nurse with responsibility for diabetes has often had little in the way of training - from what other's have said as little as an afternoon or two - in the care and management of D.
I was strongarm 'encouraged' to go to my Surgery (who had acquired a specialist Nurse) several years ago. Annual reviews were always thorough enough and I drifted along for a few years smiling and nodding through appointments whereever suggestions were made that I didn't think would help. A few years ago I got myself into a fix with a nasty hypo and trip to A&E then discovered the DOC and went back with a whole bunch of questions. She referred me to the GP with interest in D who said he was not qualified to advise and referred me straight back to the hospital (to the same clinic I'd left several years earlier).
So my GP surgery was fine as long as I just wanted to keep on carrying on, but weren't confident to switch insulins etc. The GP with special interest in D actually said that they were more 'geared up' for T2.
I know this is not the case everywhere and there are some who get brilliant care at their GP surgeries - but if you have concerns it might be worth bearing in mind that some GPs feel a bit out of their depth with the nitty gritty of T1 management.
My surgery are brilliant and very supportive. They look after blood tests, vaccinations, general health etc. They also host the eye screening via a mobile unit, but I'm more confident now I'm back under consultants/registrars.
