Borderline Personality Disorder (BPD) is a generally misunderstood condition, perceived as difficulties with emotions. However, it is one of the hardest conditions to live with. So, many people choose not to.

One study showed that approximately 1 in 10 suicides in Australia are related to a person having BPD symptoms and even calling for help [1]. The intensity of emotions during BPD episodes is unbearable. But BPD is still surrounded by stigma and misconceptions.

This article aims to spread awareness about BPD and debunk the common myths. Read more to know what BPD actually is, what a BPD episode looks like, the common triggers and symptoms, and how to manage them. Whether you’re living with BPD or supporting someone who is, you are incredibly strong.

What Is Borderline Personality Disorder?
 

Borderline Personality Disorder (BPD) is a mental health condition characterized by intense emotions and difficulties with self-image. Although it might seem like everybody has these troubles occasionally, BPD is not triggered by temporary stress and also has much stronger manifestations. BPD deeply affects daily life, influencing how a person feels about themselves and others.

Due to masking and stigma around BPD, many people go undiagnosed, and little research is done to improve diagnostic tools. What became validating and helpful for those who cannot get a formal diagnosis is an online BPD test that estimates the likelihood of a person having BPD. It should still be taken with a pinch of salt, but the results of the test can be helpful knowledge if you ever want to seek professional support.

Prevalence studies estimate that BPD affects from 0.7% to 2.7% of the general population [1]. Women are diagnosed more often. While this may reflect biases in clinical settings, researchers argue it’s because women are freer with their emotions, while men direct their BPD manifestations into antisocial behavior and substance use.

Some symptoms of BPD episodes overlap with other conditions, especially with mood disorders and signs of childhood trauma, such as bipolar disorder, complex PTSD, or depression, making misdiagnosis common. Almost 40% of individuals with BPD have been misdiagnosed earlier in life [2]. Accurate diagnosis usually requires a structured clinical interview and consideration of long-term patterns, while some clinicians focus solely on addressing symptoms.

Causes of BPD

Causes of BPD are complex. Its roots are similar to neurdivergent experiences: genetics and differences in brain development and neurochemicals [3]. The most prominent differences are seen in:

• amygdala, a brain region responsible for regulating “negative” emotions
• hippocampus, a brain region that is responsible for self-control
• orbitofrontal cortex, responsible for planning and decision making

Environmental factors, such as childhood trauma, can also contribute, but usually they are not the root cause of the disorder.

What Does a BPD Episode Look Like?
 

A BPD episode is not a “bad mood.” It’s a period of emotional intensity, either joy or frustration (more likely), that can feel overwhelming and impossible to cope with. During an episode, a person with BPD can escalate their emotions quickly. They experience shifts in mood, act unpredictably, and may hurt the people around them.

Symptoms of a BPD episode come on rapidly, either caused by BPD triggers or not, and leave the individual and those around them feeling drained or confused. What makes BPD episodes especially difficult is their unpredictability in timing and in manifestations. Depending on the situation or personality, BPD individuals can experience uncontrollable anger, deep despair, or a complete detachment from reality.

BPD Episode Symptoms

The symptoms of BPD episodes aren’t identical for every person. There are some patterns that are reported more frequently than others. Symptoms of a BPD episode usually last for hours to a couple of days. Not only does it significantly disrupt personal life and decrease self-esteem, but it can also severely impact work and generate even more stress.

What does a BPD episode look like? The most common symptoms include:

• Intense emotional shifts. Sudden transitions from sadness to anger or from excitement to despair without an obvious reason. The “urge” to rapidly shift emotions is often repressed because of how it is perceived in society.
• Explosive anger. As a consequence of unexplained mood swings, people with BPD have a hard time regulating anger. They might yell, throw objects, act actively or passively aggressive, or suppress their anger and have furious thoughts about a person. It happens when people with BPD feel misunderstood or rejected, and it is a more common symptom among men.
• Physical signs of fear of abandonment. Panic, desperation, and intense anxiety at the thought of being left alone. Sometimes, this fear might not have a ground or be exaggerated, but it feels terrifying for a person experiencing it.
• Impulsivity. Risky spending, reckless driving, binge eating, substance use, etc., are all coping mechanisms.
• Feelings of emptiness. A sense of lack of identity or motivation to do anything, as if nothing matters, can lead to withdrawal or self-destructive behaviors.
• Dissociation. Feeling disconnected from one’s body or surroundings, as if watching life from the outside.
• Self-harm urges. Some individuals may experience intrusive thoughts or engage in behaviors like cutting, burning, or scratching themselves as a way to release emotional pain.

For outsiders, these symptoms may look like overreactions, but for the person experiencing them, the emotions feel unbearable. This intensity is part of why professional support and coping strategies are crucial for managing BPD.

 

BPD Episodes Triggers

Some BPD episodes are sparked by specific events or interactions, known as triggers. These triggers are tied to the individual’s fears, past trauma, or current stressors, and they can ignite powerful emotions in seconds. While not every trigger will affect every person with BPD, several common patterns appear across research and lived experience.

What triggers a person with Borderline Personality Disorder? Typical triggers include:

• Ignoring or being deprioritized. For example, a partner not texting back or a canceled plan that triggers deep fear of abandonment.
• Criticism, real or imagined. Feedback at work or a casual comment from a friend is usually not perceived well by people with BPD.
• Conflicts and arguments. Although arguments with loved ones are a normal part of human relationships, people with BPD perceive them as rejection or a personal attack and, hence, can escalate, which leads to more relationship issues and bursts of anger.
• Stressful transitions. Stability and routines are known ways to manage symptoms of BPD episodes, but certain life events, such as moving, changing jobs, or starting school, destabilize routines. The discomforts that life challenges bring can make a person feel vulnerable, hence, “not worthy” and behind.
• Memories of past trauma. Sights, sounds, or anniversaries of painful events may bring intrusive thoughts or flashbacks.
• Loneliness or isolation. Loneliness is detrimental for everyone, but for a person with BPD, extended periods of being alone can feed their feelings of emptiness and rejection.

The intensity of these triggers usually stems from unresolved childhood experiences or attachment wounds. More examples of triggers for people with BPD can be found on this Reddit thread [4]. That’s how you may feel validated. But also remember to take information from internet forums with a pinch of salt.

Managing Symptoms of BPD Episodes
 

When an episode begins to build, the priority is not to “fix” everything at once but to calm the body and mind enough. The best tip is to take small, immediate actions that can prevent emotions from escalating and help you regain a sense of control.

Practical strategies to prevent or stop a BPD episode include:

• Distract yourself. Focus your attention elsewhere by watching a calming show, organizing a drawer, or doing something tactile like knitting or doodling. While these are among the most effective ways to interrupt intense emotions, they do not address the root cause of BPD. Instead, use them as symptom relievers.
• Try to sleep more. Being well-rested makes episodes less intense. During high stress, a short nap resets the nervous system. If insomnia is severe, consider discussing short-term sleep aids with a doctor.
• Reduce stimulation. Step away from screens, dim the lights, and wear comfortable clothes. A hot shower or bath can soothe the body and reduce sensory overload. In that way, your anger build-up eases because you reduce the number of stressors.
• Cool your body. Temperature change is associated with emotional regulation. Use a fan, splash your face with cold water, or hold an ice cube to bring down the intensity.
• Reset your breathing. Try the “4-7-8” method: inhale for 4 seconds, hold for 7, exhale for 8.
• Move your body. They say depression can’t hit a moving target. Same thing with BPD. Even a 10-minute walk outside or a good dance session at home releases built-up energy. It’s also one of the ways to distract yourself during an intense BPD episode.

The key is experimenting with these strategies ahead of time and noticing which ones calm your body fastest.

How Borderline Personality Disorder is Treated

Borderline Personality Disorder can feel overwhelming, but it is, in fact, the most treatable mental health condition. The main rule is to stick to professional support and evidence-based methods. So, how do you do it?

1. The first step is getting a proper diagnosis. A mental health professional usually conducts clinical interviews, reviews personal history, and sometimes uses structured assessments. BPD may be misdiagnosed, especially as bipolar disorder or depression, so be sure to share everything applicable with your clinician.
2. Medication may be prescribed to manage specific symptoms such as anxiety, mood swings, or sleep issues. While there is no pill that “cures” BPD, mood stabilizers, antidepressants, or antipsychotics can make emotions more manageable. That’s also one of the pathways for therapy to work.
3. In cases of severe self-harm risk or uncontrollable crises, short-term hospitalization can provide immediate safety and stabilization. Hospitals create a structured environment where intense symptoms can be addressed before returning to daily life.
4. Therapy remains the cornerstone of BPD treatment:
   • Dialectical Behavior Therapy (DBT) teaches emotion regulation, distress tolerance, mindfulness, and healthier relationship skills. It’s currently considered the gold standard for BPD.
   • Cognitive Behavioral Therapy (CBT) helps reframe destructive thought patterns and develop healthier coping strategies.
   • Schema Therapy works on long-standing beliefs formed in childhood that fuel BPD symptoms, such as fear of abandonment.
