Living with a rare form of diabetes

My A1C is 5.3 and my BMI is now overweight instead of obese....I'm doing well and all it takes is the right meds and good diet. But I will never get rid of diabetes because I have a rare chronic and genetic form that isn't even on the list on Alike. It's close to Type 2. Having a chronic illness is so unfair. It's so unfair that I have to make all the right choices to survive while everyone around me can eat whatever they want. I love food. Good food. Comfort food that makes me happy. Some people can be fat AND healthy. It's so unfair that even when I am doing well, I still worry about losing my sight, my limbs, my kidneys, and even my life. I am afraid I will die before 50. I'm only 18.
