Frozen with fear bc insurance

Why am I getting billed EIGHT HUNDRED AND SEVENTY FIVE DOLLARS for my anatomy scan?!?! I'm under the same insurance I had with my first child and I didn't pay a dime until I had to pay $1000 for my hospital bill, which I know is incredibly low. Now I need to pay almost that much for a routine ultrasound?!?!?! I'm so angry. I can't sleep, I'm afraid to go back to the doctors bc they need a second look to get better images of my baby's heart and I'm afraid I'll get charged another $875. What has this sad world come to? I've already skipped my blood testing bc that was gonna cost me $200 (was also 100% covered with my first). My deductible is $600 and was met months ago. I'm frozen with fear over what this pregnancy is going to cost me. How stupid of me to think I was fine bc my insurance was affordable 2 years ago and now it's destroying my life. Feeling like a prisoner of the insurance company. I guess my life is in their hands now that I'm pregnant in America.
