As far as I know all cortisol does is to prepare you in emergencies in an instant to act really fast rigth? But they say when something traumatic happens there's so much information that you can't handle and you have to suppress some of them. But is it really that much information you can't handle or so much pain cortisol gives to you (i always feel physical pain in my head when I get less depressed and become more aware of myself, i'm pretty sure most of you don't, and you know it kills your brain cells which reminds me of some kind of a poison too ) that you can't handle the pain and want to disassociate from your feelings of pain? And isn't it that pain you disassociated from yourself that causes the suffering after trauma?

This idea just popped up my mind and I didn't know where to ask it so I would appreciate if someone give an answer to this.
