Yes.
The brain does change with trauma, but it can keep changing after that in order to heal. We have a natural healing ability, like we have a natural healing ability to recover from a cut on the hand or a broken bone. In the same way as recovering from a cut or broken bone, we have to take some action to provide the right conditions and support that healing, and we also have to allow the healing to happen. Trauma/PTSD healing is much bigger, of course, but the healing principle is the same.
I personally think that it would be hard to completely heal with talk therapy/exposure therapy alone. I've found it essential to have somatic therapy and to work with non-verbal techniques. In my case, that has been craniosacral therapy, visualisation for safety and art therapy. Talk therapy in the right way at the right time has been important too.
I started out very symptomatic (especially startle response, terror, anger, flashbacks, nightmares and hallucinations). I no longer have those symptoms. I'm now having to look more at my childhood trauma, but as I start doing that I realise that it's no longer trauma energy I have to deal with, but the meaning of what happened. What I have to work on now is the longer term effects of living the way I have been with amnesia, dissociation and then memories/PTSD. The trauma fear and hopelessness are gone. I'm no longer afraid of the world outside or inside my head.
I don't think I'm different from anyone else. I think it's an incredibly hard journey and it takes as long as it takes. As long as we go in the right direction, though, I believe everything can be healed.
