Thankyou , I did have an initial hour long appointment with the diabetic nurse at my surgery who went through it all briefly but if I'm honest with you I think I went into denial a bit and then covid hit and I've been stress eating

or not eating much at all. My diet is pretty carb heavy and I think that's where I'm struggling even if I cut out sugar , that's the bit I find more difficult to understand. She did mention having protein for breakfast not cereal and things like that.
That's too bad: when finally someone seems know a thing or two about a thing or two (Protein rather than cereal! Yay!), their information does tend to come at a time when we're least likely to absorb any of it. When you're still in the middle of the shock of diagnosis, and going through the stages of grief (denial being one of them), everything people do say goes right over our heads. But hey, that's what the forum's for.
Sugar is a carb. But so are starches and fructose, honey etc... That makes even "natural" sugars bad, but also makes an enemy of bread, rice, wraps, cereals, potatoes, pasta, corn... The thing is though, carbs are addictive. You'll have cravings for a bit as your body does demand them, and then you'll find the cravings, for the bulk of us at least, will go away. It really does come down to kicking a habit. Some go cold turkey, some do it gradually... And if you do go that route, it's entirely up to you. For me, the faster the better, but you might want to take it slow. Your choice!
As for stress eating: Make sure you have comfort food around that isn't bad for you. Pork scratchings, nice hard cheeses, olives, deviled eggs sound good? Extra dark chocolate (85% Lindt is nice, and if you find it too bitter, have a walnut with it, or a gulp of cream), walnuts, pecans, cold cuts... Kind of like a tapas platter, without bread! You can have those and they won't ruin your blood sugars, while still being nice'n'decadent. Maybe some strawberries with unsweetened cream? (Not a whole box, mind you... She said, knowing she can't stop herself from going to the bottom of one either).
You'll get through this.
