Failed 3 hour glucose test

Has anyone failed their 3 hour glucose test?

:/ I just got a call saying that I failed my 3 hr glucose test and that im diagnosed with gestational diabetes and have to make an appt with a diabetes specialist.

I'm extremely nervous I'm an extreme picky eater and have a sensory issue where I just can't eat certain foods. Im scared I'm going to end up starving because I don't want to eat the wrong things !!!! Has anyone been diagnosed with gestational diabetes and how was that for you?
