It does sound horrible, and I am sorry you were so traumatised.
But fwiw it sounds a bit like my labour with ds2. I was at home, my ctx started just before 7am, every few minutes and kept getting closer together - by 7.15 I knew what was happening and called MW. She said wait an hour and call again, well, it carried on, I called my mother, she took ds1 away (she lived a few minutes away from us) and I called again and they sent someone out to check. Despite thinking I was imgining it, they found I was 4cm dilated when they arrived.
My whole labour was 3 and a half hours, and I asked to be transferred for an epidural as the pain was so dreadful, but they said no chance - there just was not enough time, plus my contractions were so close together they'd have trouble getting one in iyswim? Perhaps that was the case with you too - they probably were thrown by it being so quick and didn't think it would be in time. You have to stay very very still for a few minutes to have an epidural or it can damage your spinal column.
Anyway I refused the G&A as it seemed pointless and I just gave birth on the floor by my bed, thankfully with a lot of kindness and support from the (now 2) midwives, a close friend and another friend.
I felt so awful, it was too quick and I was shaking badly, I suppose I went into shock sort of, I had a heavy bleed as well which they controlled with an injection, after initial panic. I was traumatised too but thankfully it didn't last for too long. Maybe because I was at home and felt like people had done their best, that made a huge difference I think, because I felt more traumatised by ds1's birth WITH an epidural, and that was in hospital.
It was people's attitudes that counted, for me - at home I might have been in appalling pain but I was being taken seriously (well, eventually!) and supported. In the hospital I was treated like I was making a fuss, being stupid, had no idea etc etc etc.
I also had a bad reaction to the epidural the first time, and ended up being very sick for ages, and no one would come to help, I couldn't move, obviously as my legs were useless and ds was crying to be fed 
No one came for ages. Plus once you've had an epi, they strap you to a monitor and you can't feel anything or move and then the interventions start - they almost gave me a section because I couldn't feel to push.
It's not all it's cracked up to be. I do wonder if giving birth at home might be a better option for you, than going into hospital again? Just something to think about. You tend to get much nicer treatment at home ime, you feel more in control, and in hospital I felt like something on a conveyor belt - very unwelcome, laughed at, mocked, ignored. Abandoned really.
Totally different experience.
I'm having #3 at home, on midwife's advice as she thinks I'll be too quick this time to get to hospital anyway...you might be the same with your second.
