Borderline Personality Disorder (BPD) is a mental health condition characterized by unstable moods, behavior, and relationships. Individuals with BPD often struggle with intense emotions and fear of abandonment, which can lead to impulsive actions and self-harming behaviors. Understanding BPD is crucial for recognizing the link between emotional dysregulation and non-suicidal self-injury, as individuals may resort to self-harm as a coping mechanism to manage overwhelming feelings.
