There's a book by Penny Simkin called "The Labor Progress Handbook". It's a small book (though not inexpensive) and available through amazon. I really really really like this book and suggest it a lot to mamas who have had a birth that "didn't work" as expected. The book sort of walks through the whole birth process and takes a look at reasons "why" certain things may happen and things to try in each case (along with probable outcomes for each intervention).
What I especially like is that she acknowledges emotional/social/spiritual reasons for things as well as the physical ones. And her suggestions for addressing a problem/situation include focusing on those emotional/social elements as well as the strictly physical. So she covers things like anger and fear, a history of sexual abuse, cultural misunderstandings or expectations, disconnects between the mother and the birth environment, etc.
With my first birth all progress stopped at 7cm (despite those massive non-stop contractions and all our efforts) and we eventually learned that dd1 was posterior and asynclitic... her position meant she just couldn't get out vaginally. She was my first, she was big, my water broke on it's own a day before contractions began... she got well and truly wedged into my pelvis. So I focused a lot of positioning techniques to help prevent that aspect, and made sure my vbac support team were familiar with all the tricks to move a babe during the birth (included in the Labor Progress Handbook, which came to the hospital with us

).
But I also used HypnoBabies, journaling, meditative walks, and yoga to help work through the emotional concerns that came from that first birth. And I found a doula and an OB team that was very much on the same page (my OBs no longer deliver babes, but one of them trained on the Farm with Ina May and they had their own first born at the Farm... their birth story is in Ina's book.) In fact, my OBs wrote an Rx for me that included things like playing in the dirt and being very vocal/physical during the pregnancy as one means of releasing the negative energy/fears from my first birth and sort of get comfy in my body to prepare for the second birth.
I know I'm rambling, but basically... it sounds like there was a lot of negativity and unhappiness surrounding your birth experience and it's not surprising that that would have an impact on you! You might want to see if your library has the Labor Progress Handbook (or can get it through interlibrary loan) and explore different techniques for processing your birth experience as well as all the stuff that has been going on during this pregnancy! (Birthing from Within, journaling, crafting, yoga, walking, meditation, birth art, etc)
