We may be waiting a long time...
This weekend I felt compelled to reread Girl, Interrupted which is available for free as an ebook at readanybook.com. This is the personal non-fiction account of a young woman hospitalized for 18 months with a diagnosis of BPD and she was clearly having a psychotic breakdown. She describes seeing faces as lumps of clay, but objects have life and animation. The floor tile patterns disturb her and she cannot tolerate looking at them. She gnawed her hand to bleeding because she wanted to check to see if her bones were really in there. She was 18 years old. The movie was good, but IMO the book really exposes her BPD thinking and psychotic break better.
JMO but people who are so impaired by BPD or DID will encounter the mental health system between age 15-25. In a cruel twist, if successful in leaving the abusive home of origin to enter young adulthood, a person might achieve just enough safety that repressed memories of early abuse flood or swamp the individual and they end up in a hospital. BPD "transient psychotic thinking" or "psychotic breakdown" or a DID "amnesiac state" or "alter personality" that is so severe that a person at age 36 murdered their 11 year stepson by multiple means over 24 hours - JMO this is a person with a long mental health history, and a person who would be in need of hospitalization in the aftermath, not a cross country trip to dump the concealed body and then just moving on to a new life. All MOO
