SO anxious for my GD test next week!

I have anxiety generally, particularly when it comes to all things medical. I've actually been able to manage it pretty well without medication during my pregnancy, mainly due to my amazing husband who always manages to calm my anxiety. But I am SO anxious about my one-hour glucose test on Wednesday. Did anyone else have this? How did you manage it? I know there's nothing I can do - if I have GD, I have it. But I really don't want to fail the one hour test!
