BPD often manifests itself in idealization and devaluation episodes and chaotic and unstable interpersonal relationships, issues with self-image, identity, andbehavior; as well as a disturbance in the individual’s sense of self.

Their feelings about others often shift from positive to negative, generally after a disappointment or perceived threat of abandonment or of losing someone. Self-image can also change rapidly from extremely positive to extremely negative.
