That story clearly isn't about terrifying birth experiences, it's about the potential after effects.
Most women, the over whelming majority make a full recovery. Yes your body may change but that's common knowledge.
I have a horror story, I spent a month in hospital after having my daughter, and I then had to keep going back for a year, first weekly, then twice a month, and then monthly before they decided I was ok and côuld stop, for that year every single medical proffessal I encountered tried to talk me into sterilisation as I wouldn't survive another pregnancy. I was 28.
I recall going to my gp for something unrelated and as he pulled up my records, across the top, in capital and bold, was "serious pregnancy complications".
But I'm all healed now, and like most women, made a full recovery. Was it terrifying, no not really. Because when you're very ill, you don't really encounter emotion such as terror, because you're either passed out, sedated, and on heavy duty pain killers. Conscious thought isn't something you encounter.
