Need prayers

I’m 24 weeks pregnant and we were told a month ago baby was looking great . I go today to get an ultrasound of the baby’s heart bc I’ve had two pregnancies with babies with heart defects one little girl living had COA and is doing great . My other baby girl I lost at 21 weeks to Turner syndrome and a heart defect. They told me today that my baby boys heart left side was bigger than the right. And he had a bright bowel and was small. I just need some prayers so I don’t overthink and get hard on myself. I’m lost I don’t wanna lose my baby boy and I don’t wanna be stuck in the hospital for almost three months like I was with my first baby girl. I don’t know why this keeps having to me . I’m doing everything I’m supposed to do and it’s like I’m still failing . Sometimes I wish God could just sit beside me and tell me what’s gonna happen and what I need to do.
