Welcome to the forum. Perhaps you could say a bit more about your diagnosis, what your HbA1C is, do you have weight to lose and if you have been prescribed any medication as that will determine how much work you need to do to bring your glucose level down and help people make suggestions.
Many find a low carbohydrate approach is successful at both reducing blood glucose and losing weight if you need to. This link may help you with some ideas for modifying your diet, it is a low carb regime based on REAL food so no sack cloth and ashes.
https://lowcarbfreshwell.co.uk/ Low carb is suggested as being less than 130g per day total carbs not just 'sugar'. But it does it mean NO carbs.
Other people find a low calorie or shakes - based approach works to give them a kick start but whatever way you choose has to be enjoyable otherwise it will not be sustainable long term, It has to be a new way of eating not A DIET.
Increasing exercise if you can also helps.
The book or app Carbs and Cals is a really useful resource as it gives carb values of a whole range of foods and meals with portion sizes which allows you to make better choices. There are some surprises and foods which are thought to be healthy are not so if Type 2 diabetic.
Foods that are 'restricted' can be replaced with more tasty alternatives.
