What I have to add is that when I have been closely bonded to or in love with a stabilizing, respectful, and empathetic individual-be it a lover or a therapist or a psychiatrist), my symptoms greatly decrease.
One takeaway of a safe relationship is that it allows me 'an in' to a new neurology-new ways of perceiving and grounding in the world; mirror neurons at play, most likely.
After the relationship passes I do have more positive bonding skills and better 'processing skills' (of trauma). My brain has new neuropathways to call upon that are more in the forefront, that lets the past traumas recede. And my brain is still my brain-plastic as it may be.
"Cure" is not an appropriate word for PTSD, except through lobotomy or death. Providers may, with good intentions, misuse that term; and they may see a decreased symptoms while in therapy-which leads them toward the notion of cure. With therapy, I have greatly benefited-increased ability to work through triggers in a shorter time period, but not found 'cure'.
I think that rating overall PTSD 'resilience to stressors' (both subjectively & objectively) is a more accurate term to use as a measure of improvement. In that case, resiliency could be defined to 'a sense of hope', decreased suicidality, and increase in optimal functioning skills-per individual,
The right relationships, a personal commitment to transformation and continual experimentation-to find things that help me, have increased my resilience but has not cured my PTSD.
After saying that, I 'knock on wood' to keep my current positive trend going. :cool:
