Hello, I'd like to help you with your question.
If you feel she might have a personality disorder and you she is willing to get help, then therapy is the best option for her. At this point, there are no medications that address personality disorders directly, though anti anxiety
or anti depressives medications can help treat symptoms. Therapy can provide an evaluation to confirm any additional diagnosis. And therapy is the best treatment right now for personality disorders.
Your family member has just as much chance of having a personality disorder as you or I do. In other words, they do not have an increased or decreased chance of having a personality disorder just because of their existing diagnosis. It would be equivalent to having a broken leg not increasing your chances of having a cold. Both diagnoses are completely different.
If your family member is on MA insurance, they can try going to their local community mental health center for an evaluation and treatment. And evaluation is needed to diagnose any personality disorder. If she doesn't have a personality disorder, they can find out what she does have and offer the appropriate treatment. She can find her local community mental health center through the United Way or by calling her local city/county government office.
You can also help by learning more about personality disorders so you can be there for her. Here are some resources to help:
