Hello
@Irish-Chris and welcome from me as well.
You have already been given some great advice, and I can only add that if you do start to work on finding the right solution to improve your blood sugar levels you will find many benefits. I certainly did and now have much more energy and zest for life.
We are all different though and it takes time to find out what works for you.
For me, a new way of eating, and increased exercise, plus some metformin has worked. As well as cutting out all the sugary things, I cut down on the carbs particularly the ‘white’ ones (white bread and flour,rice,pasta,etc ) and mainly eat fresh fish and poultry, some dairy and nuts and have learned to love vegetables. I also found that fruit raised my sugar levels a lot, so limit to 1 portion a day - usually berries. I also try to avoid too much processed food, and to include plenty of fibre some from the veg, plus seeds and pulses. There are many good recipes to make these things really tasty.
Hope you will let us know how it goes for you and please ask about anything you are concerned about.
