How do I know if I have Borderline personality disorder (BPD)?

Borderline personality disorder (BPD) is a complex mental health condition primarily characterized by pervasive instability in moods, interpersonal relationships, self-image, and behavior. If you suspect you have Borderline personality disorder (BPD), look for a pattern of intense fear of abandonment and extreme emotional fluctuations that significantly disrupt your daily life.

What are the early signs of Borderline personality disorder (BPD)?

Many individuals with Borderline personality disorder (BPD) first notice symptoms in early adulthood. Common signs include shifting between extreme idealization and devaluation of others, chronic feelings of emptiness, and impulsive behaviors such as reckless spending, substance misuse, or self-harm. These symptoms are not just "mood swings" but are persistent patterns that affect your ability to maintain stability in work or personal relationships.

How do I differentiate normal variation from Borderline personality disorder (BPD)?

Everyone experiences sadness or frustration, but Borderline personality disorder (BPD) is distinguished by its intensity and the duration of symptoms. To assess your experiences, consider if you consistently struggle with the following:

• Frantic efforts to avoid abandonment, whether real or imagined.


• Unstable self-image that shifts your goals, values, or identity frequently.


• Intense, inappropriate anger or difficulty controlling your temper.


• Dissociative feelings or paranoid ideation during times of high stress.

How is Borderline personality disorder (BPD) diagnosed?

There is no blood test for Borderline personality disorder (BPD). Diagnosis is made by a psychiatrist or licensed mental health professional through a clinical interview, often using the criteria from the DSM-5. When speaking to your doctor, be specific about how these symptoms impact your functioning. If you feel dismissed, advocate for yourself by requesting a referral to a specialist who has experience specifically with personality disorders.

When should I seek urgent help?

If you are experiencing thoughts of self-harm or suicide, please seek immediate medical intervention. Go to your nearest emergency department or call a crisis hotline. These are red flags that require professional support, and you do not have to navigate them alone.
