Your parents should have sued them for all they were worth, or had them stripped of their license to practice.
I forgot about the traumatic event the next day, so I haven't talked about it for the next couple of years. Brain blocks out traumatic memory as a coping mechanism, thus it gave me PTSD. I only talked about it 10 years later when the memory started coming back and I noticed it was affecting my life.
Would I have become a serial killer, one who kills medical professionals, an assassin, or a trigger-happy soldier?
Yeah, those are possible for some people... I still would hope you won't tho, destroying other people's lives won't make you satisfied (only temporarily) but yeah most serial killers are like that :/
For me tho, there was one point in my life where I hated men (the doctor was a man). I couldn't even talk to my dad during those times, not even a single word, just pretend he didn't exist. And I couldn't explain why (as I don't have any idea of the PTSD yet).
Thankfully there's art. So all the horrific things I can think of (self sabotaging) can only be seen in paintings.
