masochistic personality disorder
a personality disorder in which individuals persistently and characteristically obtain gratification or freedom from guilt feelings as a consequence of humiliation, self-derogation, self-sacrifice, wallowing in misery, and, in some instances, submitting to physically sadistic acts. This disorder was listed in DSM–III–R as self-defeating personality disorder but was deleted from DSM–IV–TR. The term is controversial because many believe that in some cases it blames the victim of abuse.
