Should I be worried?

My dad's grandfather had diabetes. We have other people in the family with the same condition. My dad is starting to show signs of diabetes and he just got tested today and we are awaiting results. He smokes alot, and has ALOT of problems with digestion and etc. I am 16 myself. Should I be worried? Could this be genetic. I dont EAT OR USE sugar, but I consume alot of honey and deserts sometimes. I always put honey in hot drinks like hot chocolate or tea. I eat alot of fruits, and I dont really eat much.....
