my answer is yes, even though i do not really feel it. i do believe in the power of the mind and positive declarations. i believe in hope and visualization and talking yourself into new realities.
i also have periods of near total relief of my symptoms, and so for me the idea is now to get this phase of myself to "stick" and not slip backwards.
i do also believe on a purely practical level that the condition can be cured, and as a society we are held back (meaning- insufficient clinical attention and funding) all in a kind of collective, cyclical abuse pattern (think: war machine, poverty, poor education, systemic neglect, self-hate, guilt, poor parenting, addicted to addictions, destroyers of the environment, collective narcissism.. cruel and unusual criminal justice system etc) and so it makes it that much harder for individuals to see outside of the meta pattern to their own healing.
i wonder too about the patterns of PTSD and recovery in different countries and historically...
also i have been referred to a doctor who apparently has an 87% cure rate with ptsd, (psychotherapy, hypnotherapy) and while i have not seen him (yet?), i am thinking about it. he is half way around the world though
when all is said and done i am positive in my conscious waking and intellectual mind but still sloshing around in the bad patterns and memories and messages that operate in my subconscious.
