Gestational diabetes

So got news from the doctor today that turns out I have gestational diabetes 😓. I'm so upset about this. My diet is super healthy, I exercise daily & I take vitamins. My weight gain is perfectly normal. I give into cravings very rarely and now this. My doctor looked shocked giving me the news like she couldn't believe someone as healthy as me could have it. I'm so upset. Iv aways had a fear of needles and now the thought of having to prick myself 6 times a day before and after I eat is so upsetting. Baby is measuring out normal she said and go to sonogram apt next week. I cried for about an hour. The hormones didn't help lol but I'm scared and now worried what else I can possibly do to prevent this getting worse. When I go meet with the doctor about the GD next week I know they will teach me what I need to do and how to do it but still so discouraged. I know it could be worse. It alwyss could be worse but just need to hear from other mommies that may have been in the same boat as I have.
