From what I have read, I personally would be very sceptical in particular regarding a 'Diagnosis'.
As far as sticking to a diagnosable Mental Illness is concerned, I would be very, very cautious of anyone claiming to be an authority on this very scantily proven "Diagnosis".
I wandered for many a yea,r pondering as to what was actually wrong with me.
When I was diagnosed with C-PTSD last year I spent hundreds of hours, day and night researching proven studies into PTSD and the effects it has on the physical person that I am.
Please, please, please, if you are going down the route of spiritual explanations for the physical and psychological effects of trauma suffered as a child then be as open minded and objective as you can. Please do NOT get drawn into psycho-babble by so called professors of the "Psychic - Phenomenon".
In what-ever path you personally choose I wish you the healing you seek.
kindest regards and :hug:s if you accept them
Laurence.
