Holy S*** that is some mental yoga going on there.
Good for you but my 2pence worth is to chill a bit. Not to be as condescending as that sounds, as when I was first diagnosed I was angry, impatient and needed to understand my condition Now. Really this intensity was helping to keep my blood sugar high....all to do with physical stress response and your liver being instructed to pump out glycogen to fight or run from a suspected sabertooth encounter.
Your numbers are coming down... as a previous poster said, I think, write your food and amounts down. My fitness pal app can help with that. I haven't used it as I am old school and tend to write stuff down for 2 days and then think that's tedious and stop.
Once you add your blood glucose readings from before and after food, you will over time see trends. Its these trends your looking at. So if there is a dish you have occasionally and you notice that your BG raises the following morning. Then you might reduce what you had or avoid it or have it much earlier in the day with 30min of exercise afterwards to burn up that extra glucose in your blood.
This is the long game; the mere fact your 'eating to your meter' (the aim for no more than a 2mmol/L raise after 2 hours of eating or non-diabetic levels) you will lose weight if you have any to lose. Take up regular exercise, you will improve your numbers. LCHF on this forum you will see personal interpretation of that that either works for the individual or not. I would say I do a low carb some days <20g other days <50g, my BG can handle that flexibility right now. It might not in the future nor might it work for you; highish fat, cause I eat way more fat than I used to and even only just started having fat drinks which took me weeks to get my head around, but ultimately how I feel, what they taste like and what my meter shows, dictates stuff I eat. No biggy.
Be prepared for the NHS to not fund or recognise your aims for non-diabetic levels. My GP is convinced Type2 is a progressive disease and I'm basically ******. So that might mean purchasing your own meter and test strips. For that SD CodeFree is great. I get through a pot a week. Works out at approx £5.10 per week, with discounts. Knowing my BG numbers is worth more than 2 'flat whites' a week to me. Read books if you like, I got the Beirnstine (sp) book on kindle, but not read yet cause I prefer an urban fantasy book, I do like reading how real people with Type2 manage their own beast on the forums.....
But essentially your doing a Sinatra, your condition your way. Respect for that.
