Hi there Mark and welcome to the club that nobody wants to be in.....the diabetes club
I'm so glad that you went to your doctor and got tested at this stage because there is sooo much you can do now to prevent it getting any worse
Unfortunately for me, I didn't get any symptoms until my glucose levels went very high, so it was straight onto the medication for me.
You will be able to have a good chat with the doctor and the diabetic nurse. The nurse should be able to give you heaps of information as to what you can do for yourself right now
Mark it would be rare for you to ever need to have insulin injections, usually it can be perfectly controlled with diet, exercise and medication in the form of tablets if need be
You can also go and have a look on Diabetes UK website where there is heaps of information, plus there are various forums that you can join where you can also get lots of help, advise and support, just have a search around
Above all, don't despair or panic, it's really just a learning curve and a few changes, I've been diabetic for many years now and nothing dreadful has ever happened to me
