33 years as a family-systems and trauma-recovery therapist suggests to me that typical survivors of early-childhood abandonment, neglect, and abuse (trauma) inherit up to six psychological injuries from wounded, unaware caregivers: personality fragmenting, excessive shame, guilts, fears, reality distortions, trust difficulties, and trouble feeling, empathizing, and bonding. Until these wounds are identified, accepted, and reduced, they cause a wide range of personal and social problems, and promote illness and premature death. They also are apt to pass on to the next generation.
It appears to me that many or most "mental health disorders" are symptoms of these wounds. If this is true, then much mental-health assessment and treatment is focused on symptom relief, not wound-reduction.
I welcome your feedback on these premises.
