I didnt have a c-sect but I had a forcep delivery.
My baby was born in the 'anterior' position which meant he was coming out facing outwards with his 'face" towards the sunlight tongue so to speak, NOT his head, which is the norm. This meant that no amount of pushing would have helped him come out as he was simply stuck there.
I was 7 cms dilated and when the doc arrived he was in two minds between a c-sect or forcep delivery and in the end he opted for a forcep delivery.
He gave me an episiotomy, he said "sorry my dear but you need one" so he cut me and during the process of him trying to pull the baby out i ended up tearing as well. Needless to say the agony i felt down there , once all the drugs had worn off. I had stitches upon stitches. I lost all control of my bladder so i would pee myself everytime. I would be crying when i tried to walk or dress myself, like you said I couldnt even put my underwear on myself. I couldnt change my baby, bathe my baby, very similar to your story. My mum and my hubby , god bless them!!! They had to do almost everything until I was able to get back on my feet.
It seems to me that horror stories can happen regardless of whether you deliver naturally or by c-section
