This is a "personality disorder".
Even Bai Qinghua furrowed his brow at this moment.
Firstly, the causes of "personality disorders" are diverse and longitudinal.
Take "borderline personality disorder" for example. Congenitally, it has a hereditary tendency. Researchers have found that the amygdala, prefrontal cortex, hippocampus, and other structures connected to anger, fear, emotional regulation, and memory in the brain of those with "borderline personality disorder" are different from ordinary people;
Adventitiously, family environment, childhood experiences, school education, etc., definitely have a role too.
From a psychological perspective, under unfavorable biological and environmental backgrounds, an individual may develop maladaptive coping mechanisms (such as self-harming, substance abuse, dissociation) to deal with unbearable pain.
