what if my traumas are so deep ingrained in my childhood and those events dont terrify me anymore? i mean i know exactly those events created my personality and traits and they were very very painful for me. but more than 20 years passed and i dont feel any emotional issue for those events. priorly to my relapse i had still very deep emotional problems and codependency. but i never adressed this as a byproduct of my childhood issues. so now im depersonalized and even the more recent things dont trigger anything in me. the trauma is too deep ingrained. the wound is to hard for meBonjour! I am glad you asked. Also, good critical question.
In the last 1.5 years I have tried almost everything, all medical checks, all techniques including accepting, living life etc. However, it didn't help me at all even after committing myself to it for months. See, I am no doctor but I believe that 'trauma' is a wound which takes treatment to heal.
On your brain physical change question, I hope you have read the work by Bessel Van der kolk and Peter Levine. If not, I urge you to start today. There is so much content on YouTube as well.
Having said that, I don't disagree that people have recovered just by distraction of accepting, however, if that is not working and no significant improvements are seen even after weeks of trying. It clearly will not work for that individual. Human nervous system is still a mystery to us, what works for one might not work for another.
