I'm sorry you've had such a horrible experience.
I really feel for you. I had a day and night of contractions and pre labour and Then had a 52 hour labour (full on labour and dialating). Before an emcs.
The whole thing was a long and painful nightmare. I still have flash backs and night terrors over 4 years on.
Lots of things went wrong which I don't want to bore you with. But when they were ready to do the emcs, I was on the table and they had opened me up. At that point they called two other people as they couldn't decide how to get DD out. As in she was wedged in a funny way and they wanted to avoid hurting her so hum and ahh'd over which "way"'to get her out. Not nice and at that point after such a long labour I was convinced they were actually going to kill us both and we were about to die. I think I was screaming no and I want to go home a lot but they ignored me and focused on task in hand.
I do recall them saying that they were considering using forceps through the CS incision to help DD out.
In the end two of them stuck their hands in and manipulated DD free and out she came.
DD and I were safe. DD was and is perfect (pfb of course).
I have since had a DS by a lovely calm planned elcs.
Still though I feel for you as it was traumatic for me in lots of ways. Not just the CS part but the mistakes made during my labour. A problem on the ward afterwards with a male midwife and the fact my uterus wouldn't clamp down after the delivery and the endless silence in the operating room whilst waiting for my uterus to clamp down whilst I bled out fast. I was alone as DH had gone with DD and I was silently crying because I was so delirious I thought these people were going to kill me and I wouldn't get to hold my DD. awful.
All I am saying is even a CS can be a rough delivery with tugging and forceps. And a bad birth can leave you feeling violated and traumatised. However the staff mostly do their best and are not trying to hurt you.
I don't know the full ins and outs of your situation so I can't say whether you should think about legal action. I do think you should talk to them and your GP and see your records to gain insight.
I don't know whether councelling would help. Perhaps you just need greater insight into what happened to understand.
Again sorry for your experience.
