I think PTSD is fully healed when you can survey the landscape of that epic battle, that place where your nervous system failed you through no lack of will, no fault of your own, and see it with curiosity. This is a connection freed from the chains of horror. This is of course a follow up/continuation of my previous post.
I will add to this that battles only need to be fought once. They are won, lost, postponed, or cancelled, but only once. Ever after, you need to be either learning from them, or letting them disappear. Preferably the first, then the second.
Nothing can be worse than a battle you can’t win, and can’t stop fighting. You can’t change the past, but it can continue to change you if you give it the power to.
Never impose on yourself a guilt you would hesitate to hang on the neck of someone else. Excessive guilt is actually a theatrical way of avoiding the responsibility of growing through failure and pain.
