About thirty years ago a professor at the University of Washington was working with suicidal women, many of whom were borderline personalities. This group is notoriously difficult to treat. They usually have not just one but a large number of problems, such as self-injury behaviors, substance abuse and eating disorders, that "travel" with their personality disorder. A very high percentage drop out of therapy. Often the best a therapist could do in the 1980s was to lower a patient's number of suicide attempts, and yet that "cured" patient would remain depressed, unemployed, using drugs, involved in troubled relationships, and otherwise leading a chaotic life.
