You still have good changes of improving if you take diet seriously, my A1c was 10.5 (well ahead of you) in January (initial diagnosis).
2 months later after a very strict low carb diet and weight loss, I am no longer diabetic (by blood work analysis).
For the moment l would suggest you look up for low carb diet and keto diet... or to simplify just eat meat/fish/eggs with green leaf for 2 or 3 months than get your analysis again.
Insulin comes much later in the desease... for those with good control (maybe some luck) possibly never...
As for a glucose meter that should be the first thing. A continuous monitoring system like the Freestyle Libre 2 was an amazing learning experience so I can monitor in chart all day long with what I eat, what happens overnight etc.
I dont think that is subsidized for non-insuline patients (in UK if that is where you are)... you may have to pay it yourself (dont know how things work there).
Before I had my own meter, every Saturday morning I went to lab for measuring (it was paid out of pocket), but not expensive.
