Terrified of 8week ultrasound

I'm so scared to go to my ultra sound. I had a missed miscarriage September of 2014. I went in for my 9 week ultra sound and found out the baby stopped growing at 7 weeks. I can't imagine going and finding out the baby doesn't have a heartbeat again. It's all I think about. It's all I dream about. Any advice or experiences that could possibly ease the anxiety. Please and thank you.
