Your fasting BG is right on the diagnostic threshold of T2, 5.6-6.9 being pre-diabetic then >7mmol/L is diabetic. This needs to be confirmed by a lab draw, as your waiting on your HbA1c I'd expect you'll get both results together. Now whether you've tipped over the brink or not is only points on a spectrum. What you have is tremendous wiggle room for improvement, I was 19.5st at diagnosis so not far off yourself. Once I started low carb the weight just fell off & the bloods normalised again. If you've caught this early enough & your insulin resistance is purely down to visceral fat then the solutionlies in your hands.
Good luck.
