Hi newby, it is all a bit overwhelming and confusing in the first few months. If they are not scaring you with possible complications, its blinding you with numbers!
Your GP will sort out the Hbac1 test - it usually consists of a urine and blood test and an annual eye test. When I was disagnosed I was initially put on 3 month checks which then dropped down to once every six months and then once a year.
I was like you when diagnosed, cut everything bad out and worried about everything I ate and my sugars. I don't test every day as I am no longer on medication which gives me hypos. I go by my blood test results, the most recent was 7.1. My doc was very happy with this, although it has been lower in the past.
Its very easy for me to say, but I think its about finding the right balance between living well and being healthy. I would echo what others have said about researching different ways of eating to help your diabetes and testing them out. I have gone from a GI approach - little and often, low sugar, low fat - to the swedish diet which is low carb/high fat. It is about what works for you.
Hope this helps and good luck.
All the best
Jane
