Hi Teresa,
Not a problem at all.
You really do not need to be nervous when travelling, it just takes a little planning, just as you do everyday at home now.
When I left, I knew that I would not be coming back anytime soon, its now been 14+ plus years and I do not see myself coming back there again.
So as I knew that, I already had it in my head that I will be giving up all the diabetic medical care that I had been given the previous 8 years when I was first diagnosed. So I was prepared mentally for that and knew that I needed to find alterative insulin when abroad.
I did stock up when I left as I told my GP my intentions, I also bid farewell to my diabetic team and they even insisted of giving another appointment which of course I never attended as I said I would not at the time they gave it to me.
Something you need to remember though, as soon as you leave the country, no one from the NHS will be willing to help or assist you, so my advice is not to tell them if you contact them when you are abroad, unless you are particularly friendly with them, but on a professional level they are not allowed to help you at all, once you leave.
Now this was many years ago, so maybe things have changed in the NHS.
If I can be on any further help, please do ask and if I can honestly advise you, then I be more than happy to do so.
You live once, so follow your dreams always.
