PTSD from birth experience?

My first birth experience was a nightmare. I did not have any idea how to find a doctor I liked and that was on my side and would listen to my desires and I also did not have any friends/mom around to guide me. A really normal baby/ labor was turned into a very surgical and traumatizing experience and now that I am pregnant again I am having a lot of panic and anxiety thinking about doing it again. I am having nightmares and literally have trouble breathing when I think about it. Any one with me or have advice for me?!? Anything would be appreciated.
