I am newly diagnosed (Nov 2020), but have had to get a grip fairly quickly due to work requirements for regular medical examinations.
I was surprised that whilst very supportive and knowledgable as she is, my diabetes nurse was not interested in me doing regular BG readings. I think this is as a result of NHS policy or funding which does not provide BG meters to the masses, some may get them but certainly not all.
I was prescribed Metformin as an almost fire and forget medication, with a proposed follow up in 3 months, which was no good for me work-wise.
We bought a cheap BG meter off Amazon (Sinocare AQ Smart), and I started logging BG figures at least 3 times a day using the mySugr App, which seems quite good, but could have easily done a similar thing with Excel.
Logging helped me quickly get an idea of fasting BG each morning, and which foods affected my BG adversely, this resulted in an ability to tell the diabetes nurse that we had it under control with two Metformin a day , despite the prescription being for 4 a day.
I was confident having logged so much that the HbA1c figures would be low and we re-tested at the 8 week point with a pretty huge drop from 116 to 62, which we were pleased with.
This and sites like it are invaluable for a bit of self education , and that has helped massively to get enough (but still limited) knowledge of the subject to get it under control quite quickly.
Don't feel alone in the journey, and don't expect anyone at the Dr's surgery to help you much more than you've seen, spend a modest sum, get a BG meter and do some reading.
