Sugar test!

I have my glucose test and all my genetic bloodwork at 6:30am and here I am still up. I’m SO NERVOUS. I see women say they have passed out before! Plus I hate needles and bloodwork and I’m scared of how many vials they’re going to take. On top of that I have my regular ob app at 10:30 and he’s gunna be mad I haven’t taken the test yet well that I waited till the day of so he won’t have any results that day. I feel like a horrible mom already. I just have anxiety and irrational fears
