Diabetes is a pretty tough disease. Do you know anybody with diabetes?
My mother in law, and my father both have diabetes. Do you have diabetes?
I do not. I know family members that do, though. Do they have type one or type 2? Insulin is essential
Both are type 2. My mother in law is on insulin, but I believe my dad is diet/med-controlled. 
That's fortunate. I heard type 1 can be very problematic. Symptoms of diabetes include frequent urination and thirst.
It is very important to know the symptoms of diabetes. Are those the only symptoms you know of?
Type 2 diabetes
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. Common symptoms include increased thirst, frequent urination, and unexplained weight loss. Symptoms may also include increased hunger, feeling tired, and sores that do not heal. Often symptoms come on slowly. Long-term complications from high blood sugar include heart disease, strokes, diabetic retinopathy which can result in blindness,
line, do not incorporate functions to model endogenous insulin secretion — which takes place in people with non-insulin dependent diabetes mellitus type 2, and healthy subjects without diabetes. Nevertheless, a wide number of people with insulin-treated type 2 diabetes mellitus have reported finding the AIDA diabetes simulator of use for learning about balancing insulin and diet in diabetes. This is because many of the "principles" of insulin dosage adjustment are remarkably similar in both type 1 and type 2 diabetes mellitus, and even without an endogenous insulin secretion
