2nd C Section - need advice

I have a 16 month old and am 13 weeks with baby #2. I was and am so happy but these horrible flashbacks keep creeping into my thoughts. My first labor ended with an emergency c-section in which I had a panic attack, felt like I couldn’t breathe and lost consciousness. As I was passing out, I thought I was going to die. It was the worst feeling in the world. The feelings had lessened and I got to a good place mentally. I was tired and exhausted due to hours of labor with no epidural until it was determined baby was in stress and I needed c section. Anyways I say all this to say that my last appointment my doctor mentioned c-section for 2nd birth and now I can’t get rid of the feeling that I am going to die and I get very panicky. I am going to seek out therapy but wondered if anyone had a rough first csection but did better the 2nd time around. The doctor thinks with planning and more sleep prior I will handle it better. Any thoughts or advice from anyone would be appreciated. Thanks in advance.
