Piglet, its just a name, nothing more, nothing less. You are no different a person from when you walked into the center without the name, to when you walked out with it. Think about that, and apply it mentally, as this is the reality of the situation. I know what your saying, but your allowing your mind to take over, which is a big big no no with PTSD. You can't over-think everything, because you will only create more problems with PTSD. You had it before you went in, remember that.
The only wall you really have, is your trauma, as that is whats causing you to think another wall now exists. If you didn't have trauma, and someone told you you had PTSD, you would tell them not a chance, and nothing would change, ie. no wall would suddenly be put up. That wall technically had to exist already before you where given an official brand to your problems. That means, trauma is winning, Piglet is losing!
What are you going to do about that?
