Diabetic is a risk factor for gum disease, but it is NOT the cause of it. First, let's find out why is the gum bleeding? Because there's inflammation. Why is there inflammation? Because there are bacteria (plaque) present. Many people when they see their gum is bleeding when brushing, they will tend to avoid touching that area, this is not a correct concept. Bacteria will just build up more and more, the gum will always be inflamed, and the gum will never get better.
My advice is visit a dentist and get a proper cleaning done, and then make sure you brush properly at home (by properly, I mean brush one to two teeth at a time and move in a sequence so that you know you've covered ALL the surfaces of all the teeth.) You shouldn't feel any roughness with your tongue after you brush, the teeth should be very smooth.
The bleeding gum will get better within two weeks time, if you can improve the oral hygiene.
