Trauma from previous pregnancy

My last pregnancy was traumatic to say the least. My NIPT came back normal. When I went to my anatomy scan, my daughter was measuring small. As the pregnancy progressed her growth slowed further down and I was eventually referred to maternal fetal medicine. We came to the conclusion that she likely had skeletal dysplasia and we couldn't be sure that it wasn't lethal. Since i was referred so late, an amnio wasn't on the table since I was about to be induced. My little girl was born shortly after via emergency c section due to her heart rate plummeting. She was diagnosed with Down Syndrome. She needed open heart surgery approximately 5 months later. There were several times we weren't sure she would make it. She became septic and needed a central line. Almost 5 years later, i am pregnant with baby number three (her little brother or sister.) We had the NIPT this time again since false negatives are rare, and when that happened our office switched to a new NIPT test. It was drawn about 8 days ago, received at Natera 4 days ago and i keep anxiously checking for results. It can take until 11/05, but a lot of people are getting them on day 4-5 and i keep having nightmares. I keep having vivid dreams that this baby's NIPT is going to come back positive for something. I love my daughter very very much. I wouldn't change her if I could. But of course, i just want some normalcy for our last pregnancy and i'm honestly not as afraid of t21 as I am something like trisomy 13 or 18. The nightmares are specifically about it coming back positive for trisomy 18. Every ultrasound i'm having panic attacks that they will find something.. i knew to an extent it would be hard but i did not expect the flashbacks, the nightmares, the fear with every ultrasound, lab draw etc....
