Diabetes question?

I am 30 years old and I have a strong family history of diabetes in maternal and paternal sides. My grandma had amputations from gangrene due to diabetes and the list goes on and on from effects from this disease. Anyways I just went to my dr and was shocked when my level was 104 considered pre-diabetes. Does this mean I have or will be getting diabetes soon? I am panicking about this. I am overweight but started working out and trying to eat better. Am I destined now? ONly people who know about diabetes pls answer
