Hi
Welcome to the site.
I was diagnosed earlier this year and it took me a good few months to get my head around it.
I have started to eat low carb and walk a couple of miles a day which is helping me a lot and my last bloods showed improvement which I was very pleased with.
You need to set yourself a routine of eating whats good for you throughout the day and you will soon get used to it.
Its a difficult time when you are diagnosed, but you will get yourself sorted out and fully on track soon Im sure.
