A person may develop a personality disorder as a coping mechanism for extreme or excessive abuse, abandonment, ridicule, neglect, or other childhood trauma. Since personality disorders tend to stem from early-in-life relational trauma, people who are diagnosed with one may also be diagnosed with another or exhibit overlapping traits. For example, someone with borderline personality disorder may have experienced significant abandonment as a child, like if their parent went to prison for life or consistently failed to provide emotional support. As a result, they internalize the belief that everyone will leave them and, when triggered, act based on that overriding fear, Smith previously told Insider. Do you think that parental care is the greatest gift you can give to your kid ?
