Borderline personality disorder (BPD) is defined as a mood disorder that affects one's interaction and relationships with others. It generally develops during adolescence and persists into adulthood. It has been seen that those with a traumatic history of neglect or emotional, physical or sexual abuse are more prone to developing it. Though it affects people varyingly, these are some symptoms that help diagnose BPD.
1. Emotional instability - Intense feelings of rage, sorrow, anger, guilt and emptiness or loneliness are experienced by some sufferers of BPD. Extreme mood swings, lasting for a short span of time, are common in BPD. They may also have issues with their self-image where they cannot place themselves and don't know what they feel about themselves or who they are.
2. Disturbing thoughts - One may experience disturbed thinking and the range of severity is rather wide. One may question his or her existence and need constant reassurance to believe other, or hear voices that tell one to harm oneself or others. In some cases, hallucination and developing delusional beliefs become a common phenomenon that greatly upset the mental condition of the sufferer.
