Nervous for level 2 ultrasound

I have an ultrasound tomorrow morning at the hospital because at my anatomy scan they found out baby has a single umbilical artery and a bright spot in her heart. After crying and feeling depressed for over a week, I got over it and now I'm starting to feel scared all over again.. and I am feeling really alone right now. My husband won't be able to come with me because he is working out of town and I just know my anxiety is going to be through the roof.
