I was diagnosed with juvenile diabetes at the age of 6. I remember being depressed at that age with realizing I had to take shots for the rest of my life and watch everything I eat. That was 26 years ago. Since then, I have learned to live with diabetes and realize that it really doesn't limit me too much. Sure, I have to watch what I eat, check my blood sugar and take shots, but in the large scheme of things, it's not that bad. It takes a bit of time to find a pattern for your body to follow, but once you get into that pattern, it's very easy to manage.
Life can always be worse. Diabetes is a dangerous disease, but it doesn't have to rule your life. Talk to your doctor about your concerns, track your blood sugar and he will help you get into a routine.
Diabetes is not the end all/be all. It's just a disease that you have to live with.
Diabetic for 26 years and have had no problems due to it.
