Welcome to the forum
Yes just over the threshold for a diabetes diagnosis but perfectly doable by adopting a low carb approach, no need to go low fat from the diabetes point of view as many find that the lowering of carbs makes an improvement on cholesterol level.
Have a look at this link for good explanation and some menu ideas to suit different tastes and budget.

Low carb does not mean NO carb but it is suggested that no more than 130g carbs not just sugar is a good starting point.
Getting used to looking at the nutritional labels (usually on the back) on packets, tins etc or on the internet for the carbs will give you an idea of where the big hitters are and you can cut them out or have in reduced portions or infrequently.
Remember it is all carbohydrates which convert to glucose not just sugar so it is misleading to think of it as low sugar rather than low carbohydrate. Fats and protein do not readily convert to glucose so basing meals on meat, fish, eggs, cheese, dairy, vegetables, salads and fruit like berries with only small portions or none of the high carb foods like potatoes, rice, pasta, bread, breakfast cereals, tropical fruits, as well as the obvious cakes, biscuits, pastry, sugary drinks including fruit juice.
