I suspected you were misdiagnosed Elaine - can't tell anyone why or how but I seem to have a bit of a 'nose' for it somehow. LOL
We DO get better support generally with the T1 label - and no it's not right - but it IS true. My other mate had terrible trouble with her Basal, not being able to adjust it well enough to sort her errant BGs out properly, even after she was re-classified correctly as T1. So I said well why not try a pump. Oooh, I won't get one, I'm too old. Nah, you won't, will you? I said - cos you won't ASK for one or even say you'd be interested if you could have one! Funnily enough, a few months later - she had one - when I was still on the waiting list for mine!
Doors open up. You should apply to go on a Carb Counting course - you may think you know all about it but I'm afraid you don't - otherwise - you'd have been able to 'recalibrate' your own basal insulin dose(s) ! I thought I knew everything too, after 30 years. Nope! It was a revelation to me - cos it's actually all perfectly logical and makes 100% sense ! Just needed to be explained by someone who actually had the expertise to do it without making you feel like you were being talked 'at'.
And by the way - GP surgery nurses (in the main, though there are SOME good uns) should not be trying to give expert advice to diabetics, for the simple reason they are not experts - they absolutely don't get either the training or the experience a Specialist Nurse (in any branch of medicine) has to have in order to attain the standard of the extra qualification. University course, pass the extra exams, and working full time throughout in a specialist clinic, normally in a teaching hospital.
Last thing I want to say now is, quite a few years ago at a Diabetes UK Professional Conference (annual get togethers with the great, the good and as many diabetes medical staff they can cram in and are willing to pay the cost) with various seminars. there was one, presented by several proper DSNs called "If you ask me - what this patient needs, is a SERIOUS listening to!" - at which I would have loved to have been a fly on the wall ! Proper DSNs, who understand what it's actually like for their patients, having diabetes, in the real world!
