@daphne1 Labor and delivery nurse here. I don’t know all the details of your case, but I’ll give my impression based on how you’ve described it.
Nurses, midwives, and doctors see lots of complicated cases. By that standard, your experience is not super uncommon, nor does it sound like it was particularly dangerous/life threatening for you or your baby. For example, your baby was born at term, vaginal birth and not surgical or instrument-assisted birth, no underlying medical issues like high blood pressure or diabetes, no infections, hemorrhage, or NICU stay. (At least, none of those things were mentioned.)
However, that doesn’t diminish the fact that it was a frightening and traumatic experience for you, and your doctor shouldn’t make you feel wrong for feeling that way.
The vast majority of second births are significantly easier and shorter than the first. Your experience could have happened even without an epidural, and it can be hard to know why progress was so slow. Many times it’s due to the baby being in a wonky position. With PROM, the baby’s fluid cushion is gone meaning they have less wiggle room to get into a better position. That could also explain why your uterus seems to have been working so hard right from the start, to turn baby to the correct position. I’d recommend looking into Spinning Babies and optimal fetal positioning if you become pregnant again.
I wouldn’t necessarily let your experience sway you against having another child, or getting an epidural again if that’s what you decide to do at that point. If you do want to try without an epidural, I’d highly recommend getting a midwife (they do practice at hospitals!) and a doula to help you get through natural labor.
As for tearing, you might tear again (often a tear will form along the line of the preexisting scar tissue) or you might not. For the prolapse, I’d look into pelvic floor physical therapy.
