High glucose results? + any gestational diabetics?

Cross posting this from the gestational diabetes group, this time not anonymously so sorry if you've seen this before.
I just got my results and my sugar came back as 144, standard listed as below 139. I'm so worried I can't eat or go back to sleep. I've heard babies with diabetic moms have higher risk for some scary stuff. My question is, anyone else tested high? Did you end up okay on the second test? If you did get diagnosed with gestational diabetes, how are you dealing with it, both medically and emotionally? I know it sounds horrible, but besides being worried sick about the baby, I also can't shake the feeling that I've already failed my baby as a mom. Any support would be awesome. I've been stuck in bed crying for two hours now.
