Failed the 1 hr glucose...

E
So I just heard back from my dr that I failed the one hour glucose test... Royally!! Normal range is 70-139 and mine was 193. I'm pretty bummed so now I have to go back for a 3 hr test. I'm quite nervous. I know it's common to fail the first and pass the second but diabetes runs in my family so I'm more nervous I'll be doomed with it. Trying to see the positive side of it that it'll get me on track for healthier eating, but so hard when junk food sounds so much better. Anyone else fail   The first one this bad then pass the 3 hr?
