You will slowly come to terms with the fact that you have diabetes, it's not a big deal, you just need to eat properly and do some excercise. Buy a meter and strips ( or get them free from the Doc.) and start doing a few tests. Fasting in morning, 1 hour and 2 hours after eating and keep a record of what you ate and what the test figures were.
You will soon work out what you can or cannot eat.
I only test about twice a week now, I know what I can eat so don't need to test.
Fasting reading of around 6 mmol or below I think is good, 7 mmol and above is not so good but it is a lot lower than some on here so all in all 7.5 is not a disaster. Aim for about 7 - 8 mmol 2 hours after eating ( or lower if you can). These figures are my personal goals, you may need to set yourself higher or indeed lower goals in consulatation with your Doc.
You will need to take control of your day to day management of your diabetes (probably type 2) and let your doctor know you want to do this. In short, "keep your eye on the ball", it seems like your Doc is good and has diagnosed you early. That's good, you can look forward to achieving good control and living a normal life.
Ask your Doc. about any other medications that may be benificial, there are someto protect you from other possible complications.
Keep researching on here and elsewhere, soon you will be an expert
