Certainly, meet with your physician and map out a plan of treatment.
Start with daily exercise, even a little helps. In many cases even a 10 pound weight loss can have an impact. Try to control your intake of carbohydrates/sugars, even a little helps. A lot of people find that a simple small reduction of "white" foods can help (potatoes, bread, pasta, sugar). Think portion control, not completely exclude something from your diet. Don't go overboard or you won't be able to sustain your new good habits. If you feel deprived, you increase your chances of falling off of the wagon. Feel free to treat yourself with a favorite food, in small portion, for your good work during the week.
Diabetes can be treated and controlled, but you have to be an active participant in your own care.
