The four stages of BPD, often referred to in the context of recovery, are: Emotional Vulnerability: The individual experiences intense emotional pain and feels powerless to manage it. Behavioural Dyscontrol: The pain leads to impulsive and harmful behaviours as a means of coping. Reflective Self-Understanding: The individual begins to understand their behaviour patterns and the emotions driving them. True Self-Reliance: The individual develops healthier coping mechanisms, leading to more stable relationships and a sense of self-identity.
