Personality disorders are long-term patterns of behaviour and inner experiences that differ significantly from what is expected and fall into three major groupings.
Borderline personality disorder is a pattern of instability in personal relationships, intense emotions, poor self-image and impulsivity. A person with borderline personality disorder may go to great lengths to avoid being abandoned, engage in self-harm or have repeated suicide attempts, display inappropriate intense anger, or have ongoing feelings of emptiness.
Some people describe BPD like an exposed nerve ending, as small things can trigger intense reactions. If you’re in a relationship with someone with BPD, it may feel like a rollercoaster or extreme highs and extreme lows with rarely anything in between.
