Those who are diagnosed with Borderline Personality Disorder have at the roots of their insecure attachment a rage that is often the source of so much abusive behaviour. Insecure attachment, one of the major root causes of BPD, leaves those with BPD recreating the ruptured relating they experienced that caused their emotional development to arrest resulting in the lost self – the loss of authentic self that is then supplanted by a false self that has no understanding of healthy or consistent relating.
