hi Anja
Welcome to the forum, any questions you need to ask concerning NHS Diabetic care..feel free to ask you will find a lot of people will be able to help you on here.
The Diabetic care in the UK seems to be varied from my experience depending on where you live..a bit of a post code lottery.
Saying that I have fantastic care where I am now and I hear a lot of other people saying the same...overall though you will get looked after and your meds will be free if you are Type 1 ,well you may have standard prescription charges in some parts of the UK ,not in others.
It would be nice if you could join your husband while he is in the UK, it would be an adventure for you.Please don't let your diabetes hold you back if you can.
I wish you all the best
