It would be difficult for me to continue discussion unless I can reply to other's posts... and I, too, need to be assured that I wouldn't be attacked for being misunderstood and accuses of attacking whomever I am replying to...
When PTSD is recently
caused so-to-speak it is easier (though not necessarily easy) to retrain the brain. (To me, the mind is different than the brain.

) When a trauma occurs, the brain is like, instantly frozen in time for "a second" don't take me totally literally here I'm having trouble choosing my words too) Anyway, at that point in time the brain doesn't file the memory like it normally would. Nor does it file similarly felt/experienced events (though not necessarily traumatic) correctly...
the less time between the ensuing event, and the beginning of therapy, the less time the brain has to misfile... the less the brain misfiles... and the "easier" it is to get back on track.
When I say no cure, it's referring to complex ptsd that is ingrained... and yes, there is "better" there can be improvement, there can be relief by many and return to what feels like normal life... but... at any time the brain can misfire and misfile... and associate a non-related incident to a previous trauma related incident... and.. well... PTSD is still there.
This disorder is like no other. Just like we wouldn't tell someone who is depressed to snap out of it, we probably would do best by realizing that without expert help with the ptsd, the mind has a brain of its own, and whatever it seems to be isn't easy to change.
