I don't think a person totally heals from childhood abuse.
But I do think it helps to release the miserable events
from within: I call it emptying out and/or releasing pain.
Some things you learn to live with. And some things you never
get over. There are flashbacks. Word associations bring
events forefront in the mind. You're easily hurt. You're super
sensitive, in some areas. But sharing with those who have been
through similar circumstances, seems to help ease the pressure
of the pain, which builds up with time. It's like any wound,
if poisonous toxins are NOT released, it just festers and gets worse. Ease the pressure and at least you get some relief.

I haven't had time to listen to that "Assault" video but I will!
