“I ruin every relationship I care about.” - BPD

Borderline Personality Disorder (BPD)

Licensed therapist Kati Morton explains BPD, emphasizing that it is often stigmatized and that a diagnosis does not mean someone is “broken” or incapable of having healthy relationships. She describes BPD as a persistent pattern that can be managed through treatment and skills. Improvement may be better understood as remission rather than the condition simply disappearing.

Diagnosis and the Nine Criteria

Morton reads and interprets the DSM criteria. In her account, diagnosis involves a longstanding pattern of instability in relationships, self-image, and emotions, along with impulsivity. The pattern must occur across contexts and meet at least five of nine criteria. She cautions against diagnosing oneself based on one or two symptoms and recommends assessment by a mental-health professional.

The nine criteria discussed are:

1. Strong efforts to avoid real or imagined abandonment. Fear of being left may lead someone to cling to others, keep them at a distance, or act in other ways intended to preserve a connection.
2. Unstable, intense relationships. A person may shift between idealizing someone and devaluing them—a pattern commonly called “splitting.” Relationships can feel especially turbulent because fear of abandonment and all-or-nothing judgments may reinforce each other.
3. Unstable identity or self-image. Someone may feel uncertain about who they are, what they like, or what they want, or may adopt aspects of other people’s identities.
4. Impulsivity in potentially harmful areas. Examples include spending, sex, substance use, reckless driving, and overeating. Morton notes that impulsive actions may briefly soothe distress but can be followed by regret and further distress.
5. Repeated suicidal behavior, threats or gestures, or self-harm. She stresses that self-harm can occur outside BPD as well; its presence alone does not establish a BPD diagnosis.
6. Rapid emotional shifts or strong mood reactivity. The episode describes these shifts as often lasting hours and sometimes days, distinguishing them from bipolar mood episodes while noting that accurate assessment matters.
7. Chronic feelings of emptiness. These may be associated with loneliness, an uncertain sense of self, or difficulty feeling genuine connection.
8. Intense or difficult-to-control anger. Anger may be expressed outwardly or turned inward; it can damage relationships, work, and a person’s sense of safety.
9. Stress-related paranoia or dissociation. Under high stress, someone may become unusually suspicious or feel detached from themselves or their surroundings. Morton describes dissociation as varying widely in how it feels and how long it lasts.

Relationships, Boundaries, and Different Presentations

Morton explains that someone who fears abandonment may also push people away, sometimes to end a relationship on their own terms rather than risk being left. She also discusses what clinicians may call a “quiet” presentation: symptoms such as anger or distress may be directed inward instead of expressed outwardly. She notes that “quiet BPD” is not a separate DSM diagnosis and that people’s experiences differ.

She argues that healthy relationships are possible when a person recognizes their patterns, takes responsibility for their actions, and works on managing symptoms. For partners and others close to someone with BPD, she recommends clear, consistent boundaries. She frames boundaries not as walls but as communicated expectations that help everyone know what to expect. She advises maintaining agreed limits, explaining them clearly, and discussing any exceptions.

BPD and Other Conditions

Morton notes that BPD can be confused with or coexist with other conditions:

• Anxiety: Anxiety may involve broad, persistent worries, whereas BPD-related fears may focus particularly on abandonment and relationships. They can occur together, but are not the same condition.
• Bipolar disorder: Both may involve mood changes, but the episode describes BPD mood shifts as generally faster and reactive. A clinician should distinguish them rather than relying on one symptom.
• ADHD: Some experiences—such as impulsivity or rejection sensitivity—may seem similar, but attention difficulties, hyperfocus, and time blindness are not BPD criteria.
• PTSD and complex trauma: Morton describes a substantial overlap between PTSD and BPD and suggests that trauma can contribute to BPD-like difficulties. She also mentions a rough prevalence estimate but says she is unsure of the figure. Her account should not be taken to mean that trauma is present in every case or that it invariably causes BPD.

She also discusses transgenerational trauma and refers to animal research as an illustration of how effects associated with trauma might be passed between generations.

Treatment and Coping Approaches

Morton says BPD can be treated and managed. She describes recovery as reducing symptom intensity and gaining more space between an emotional trigger and a response—not becoming perfect or never experiencing difficult emotions.

Dialectical Behavior Therapy (DBT) is highlighted as a treatment developed by Marsha Linehan, who has BPD. Morton outlines four DBT skill areas:

• Mindfulness: Notice emotions, bodily states, and reactions before responding automatically.
• Distress tolerance: Get through an intense moment without making it worse through impulsive action. Morton describes postponing a reaction until a safer time and returning to the issue later. She also cautions that alcohol can reduce self-control and make reactive behavior more likely.
• Emotion regulation: Learn to understand and manage intense emotional responses.
• Interpersonal effectiveness: Communicate needs, make requests, and navigate relationships more effectively.

She mentions practical checks and skills, including STOP, HALT (checking whether one is hungry, angry, lonely, or tired), and ABC PLEASE as ways to notice vulnerabilities and support resilience. She also refers to DEAR MAN as a communication tool for expressing needs and requests.

Other approaches she discusses include:

• Mentalization-Based Therapy (MBT): Build awareness of one’s own thoughts and feelings and consider other people’s perspectives.
• Schema therapy: Identify longstanding beliefs and patterns, including fears of abandonment or emotional deprivation, and work with needs that may have gone unmet.
• Transference-Focused Psychotherapy (TFP): Notice recurring relationship patterns as they arise in therapy and use that understanding to work on relationships outside therapy.
• Other therapies: She mentions cognitive behavioral therapy and trauma-focused approaches such as EMDR and somatic experiencing as possible options, depending on the person and their needs.

Morton says there is no medication specifically approved to treat BPD itself, but medication may help some symptoms for some people. She recommends discussing medication with a psychiatrist rather than treating her examples as prescriptions.
