Hi Shell,
What you are going through is quite usual. Loads of us have experienced this... you think you've got your readings, doses, etc, perfect, then for no discernable reason your levels end up all over the place.
I'm similar to you... have been diabetic for 5 years and have struggled to get my hba1c below 8.4. I have been religiously carb counting, writing down every insulin injection, every bit of food I eat, every piece of exercise I do, and still wasn't getting anywhere.
I ended up asking about pump therapy and the nurses and consultant were all positive about it. That was about 8 months ago. Once in the system, I've followed all the advice and gone to the sessions they have run and I'm getting a pump in January. I too live in Hampshire - where abouts are you? I go to the l(Hospital name removed) hospital. I think the care team there is amazing.
Drop me a line if you want to chat more - personal message is fine too. Any questions please ask - I'd love to help you if I can ... I'm really excited about getting my pump. I think it's a brilliant offering if you can get it. I reckon I can probably tell you the right things to say :wink:
Sam.
