There is no cure for PTSD at this time. Experts don't even know where "it" happens in the brain... any PTSD might ease but it's always there waiting, lurking..

Therapy needs to retrain the brain on how to process memories. I liken it to when trauma causes PTSD, all the memory files of the mind are dumped on the floor and scattered.... one memory leads to another and another trigger etc. The brain needs help in filing the memories. The good part is that once you correctly file a memory, the brain will find all the similar memories on that floor and file them as well.... so you don't have to go through every memory in your life.

The most important part of therapy, imo, is to go slowly. When you're stressed out that isn't the time to do memory work... and if you go too fast in therapy that's when you are really triggered and overwhelmed and wanting to quit and all that. Like the tortoise and the hare---going slower gets you "there" faster.

Learning good habits over time is what gets you through times of flashbacks and triggering... practice/repeat over and over the methods of coping the T teaches you...so they kick in automatically when you're triggered and can't think.
