can anyone tell me if there are any differences in type 1+2. ie. eyes, feet, diets, cholesterol, retinopathy and any other conditions associated with diabetes. I have just had an argument with my sister who says I should'nt be on insulin as I'm type 2 (but have other medical problems), she thinks the doctors and dsn have made a mistake and I should be type 1 instead, I am now concerned what i am??
