Yes, it's okay to cry and to worry. As a mother I too was worried about my son's health. During pregnancy, I was diagnose with it. Luckily, my son didn't have it.

Continue to follow directions from your doctor.

I also heard, praying does help.

Yes, it is. If you are being followed by an obstetrician and you are doing everything according to plan, chances are very good that your baby will be fine. Babies of diabetics tend to be bigger than average. You sound pretty healthy to me. Just get checked regularly, keep taking great care of yourself, and try not to worry so much. Tests done; for example, bloodwork will indicate if your blood sugars are changing or if the baby is having any problems. Please talk to your obstetrician about your concerns. Also talk to your mom, your sister (as you are going through pregnancy together), and to your friends. Your sister may be a bit afraid of problems with her baby too. Every pregnant woman worries. Good luck to you. And to her. And update us on your progress. I cannot wait to hear about your birth this autumn.

It is okay but like you mentioned in your other post about her crying frequently, so you should at least avoid when she is crying. She has her own baggage.
