Post traumatic and Pregnancy?

I have had counselling after the birth of our third child because it was so traumatic for me (I couldn't hold her because I was shaking so much and almost hurt her coming out, hubby told me I wasn't even with them for the last few mins of giving birth) and I was diagnonsed with PTSD. I had my first antenatal at the hospital last week and told them about my history and that I wanted to have an epidural this time, the midwife told me it takes about an hr for the epi to work, when I told her I had to have an emergency one with our first, because she was stuck, she changed her tune (she must have out 2 and 2 together and realised that I knew it didn't take an hr for it to take effect). I'm absolutely terrified of giving birth this time around, yet when I tell the doctors or midwives they don't listen to me. I'm just wondering if anyone else has had PTSD after giving birth and how the doctors and midwives treated you when you were pregnant with your next one?
