need some input!

I just found out that I'm pregnant, and I am absolutely terrified of giving birth! I have zero pain tolerance. And I'm so scared of something bad happening during birth, either to my baby (breech, umbilical chord wrapping around him/her) or to myself, like serious complications. (I suffer from anxiety so it's not easy to make these thoughts go away :(   Anyone who has given birth, can you please give me some advice?!
