There is considerable stigma and a prevalant attitude among many professionals, let alone people diagnosed with Borderline Personality Disorder (BPD), that BPD is intractable and cannot be recovered from.
There are many theories as to the cause of BPD that are being forwarded by professionals. There is even an on-going debate about what BPD should really be called. There is this energy invested in all of the theories, all of the ideas about what this mental illness challenge is called or should be called to the point that the related distractions for those with BPD may in fact be blocking their chances for recovery.
