Difficult one, I understand. But I've been past it extensively.
I've no PHd, but might suggest much further research into:
Autism / Asperbergers
Borderline Personality Disorders
Functions of the Left Amygdala in the brain
Not for the faint hearted, you may need University research
- even a brain CT scan.
Your average Psychologist, Priest, or Excorcist can't hack it.
