I am ONE year in and awaiting my MOT! I lost a ton of weight on Metformin 500mg twice per day and I am now on just the one although I can operate "lean diet" on NONE! Like just about every new diagnosed it take a while for the reality to settle and confidence to return and like you, I was sent off with a magazine and basic advice on diet and exercise.
ERR HELLO.... How do I check my progress? After a bit of support, well a lot on here actually, I bought a Codefree Meter and Strips from HomeHealth UK. I am T2 and I guess not that severe.
I test in the morning on waking and before my evening meal. The GP and Nurse will probably poo-poo me doing it but its all about MY piece of mind NOT theirs.
I love food and turning a negative into a positive, I have loved experimenting with it, pretty well impossible without having the ability to test. Also being a cyclist again I found that I need to test every twelve miles or so because it drops the BG level quickly. Someone said that if you follow a diabetic food regime and are on meds it would fall far more quickly than it would if you were NON diabetic.
As for your reading of 7.1, you need to consider where that sits over say a week. Its not amazingly high as a one off result. In the first six months as my body adapted to having to monitor food and the Metformin I measured on waking and two hours after each meal, it proved a good benchmark indicator of the "trends" and what foods I loved that I would have to kiss goodbye to or more importantly, control in terms of the portion size I could eat!
The reality is that Diabetes is a life long condition for most who are diagnosed with it. Its all about managing YOUR position with it and it will take a bit of time. Confidence is the biggest thing to gain. People say their diabetes has "gone away." As I said I can run on no meds and get my BG levels around normal if I eat like a mouse and enjoy flavoured fresh air. Kick off with a metering regime for the next six months or so on "waking" before anything else, couple of hours after lunch, before you go to bed. keep a record of what you eat each day meal by meal. You will soon settle into a path and your confidence will be good. Above all keep posting questions on here... It helped me no end!
