Borderline personality disorder (BPD), also known as emotionally unstable personality disorder (EUPD), is a personality disorder characterized by a pervasive, long-term pattern of significant interpersonal relationship instability, a distorted sense of self, and intense emotional responses. People diagnosed with BPD frequently exhibit self-harming behaviours and engage in risky activities, primarily due to challenges regulating emotional states to a healthy, stable baseline. Symptoms such as dissociation, a pervasive sense of emptiness, and an acute fear of abandonment are prevalent among those affected.
In psychology, codependency is a theory that attempts to explain imbalanced relationships where one person enables another person's self-destructive behavior such as addiction, poor mental health, immaturity, irresponsibility, or under-achievement.
A love–hate relationship is an interpersonal relationship involving simultaneous or alternating emotions of love and hate—something particularly common when emotions are intense. The term is used frequently in psychology, popular writing and journalism. It can be applied to relationships with inanimate objects, or even concepts, as well as those of a romantic nature or between siblings and parents/children.
Dialectical behavior therapy (DBT) is an evidence-based psychotherapy that began with efforts to treat personality disorders and interpersonal conflicts. Evidence suggests that DBT can be useful in treating mood disorders and suicidal ideation as well as for changing behavioral patterns such as self-harm and substance use. DBT evolved into a process in which the therapist and client work with acceptance and change-oriented strategies and ultimately balance and synthesize them—comparable to the philosophical dialectical process of thesis and antithesis, followed by synthesis.
Psychological pain, mental pain, or emotional pain is an unpleasant feeling of a psychological, non-physical origin. A pioneer in the field of suicidology, Edwin S. Shneidman, described it as "how much you hurt as a human being. It is mental suffering; mental torment." There are numerous ways psychological pain is referred to, using a different word usually reflects an emphasis on a particular aspect of mind life. Technical terms include algopsychalia and psychalgia, but it may also be called mental pain, emotional pain, psychic pain, social pain, spiritual or soul pain, or suffering. While these clearly are not equivalent terms, one systematic comparison of theories and models of psychological pain, psychic pain, emotional pain, and suffering concluded that each describe the same profoundly unpleasant feeling. Psychological pain is widely believed to be an inescapable aspect of human existence.
Complex post-traumatic stress disorder is a stress-related mental disorder generally occurring in response to complex traumas, i.e., commonly prolonged or repetitive exposures to a series of traumatic events, within which individuals perceive little or no chance to escape.

Splitting is the failure in a person's thinking to bring together the dichotomy of both perceived positive and negative qualities of something into a cohesive, realistic whole. It is a common defense mechanism wherein the individual tends to think in extremes. This kind of dichotomous interpretation is contrasted by an acknowledgement of certain nuances known as "shades of gray".
Mentalization-based treatment (MBT) is an integrative form of psychotherapy, bringing together aspects of psychodynamic, cognitive-behavioral, systemic and ecological approaches. MBT was developed and manualised by Peter Fonagy and Anthony Bateman, designed for individuals with borderline personality disorder (BPD). Some of these individuals suffer from disorganized attachment and failed to develop a robust mentalization capacity. Fonagy and Bateman define mentalization as the process by which we implicitly and explicitly interpret the actions of oneself and others as meaningful on the basis of intentional mental states. An alternative and simpler definition is "Seeing others from the inside and ourselves from the outside." The object of treatment is that patients with BPD increase their mentalization capacity, which should improve affect regulation, thereby reducing suicidality and self-harm, as well as strengthening interpersonal relationships.

He is a Professor of Contemporary Psychoanalysis and Developmental Science Head of the Division of Psychology and Language Sciences at University College London, Chief Executive of the Anna Freud Centre, and a training and supervising analyst in the British Psycho-Analytical Society in child and adult analysis.

Personality disorders (PD) are a class of mental disorders characterized by enduring maladaptive patterns of behavior, cognition, and inner experience, exhibited across many contexts and deviating from those accepted by the individual's culture. These patterns develop early, are inflexible, and are associated with significant distress or disability. The definitions vary by source and remain a matter of controversy. Official criteria for diagnosing personality disorders are listed in the sixth chapter of the International Classification of Diseases (ICD) and in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM).
Personal boundaries or the act of setting boundaries is a life skill that has been popularized by self help authors and support groups since the mid-1980s. Personal boundaries are established by changing one's own response to interpersonal situations, rather than expecting other people to change their behaviors to comply with your boundary. For example, if the boundary is to not interact with a particular person, then one sets a boundary by deciding not to see or engage with that person, and one enforces the boundary by politely declining invitations to events that include that person and by politely leaving the room if that person arrives unexpectedly. The boundary is thus respected without requiring the assistance or cooperation of any other people. Setting a boundary is different from issuing an ultimatum, though ultimatums can be a part of setting boundaries.
In psychology, manipulation is defined as subterfuge designed to influence or control another, usually in an underhanded manner which facilitates one's personal aims. Methods used to distort the individual's perception of reality may include seduction, suggestion, and blackmail to induce submission. Usage of the term varies depending on which behavior is specifically included, whether referring to the general population or used in clinical contexts. Manipulation is generally considered a dishonest form of social influence as it is used at the expense of others.
Emotional blackmail and FOG are terms popularized by psychotherapist Susan Forward about controlling people in relationships and the theory that fear, obligation and guilt (FOG) are the transactional dynamics at play between the controller and the person being controlled. Understanding these dynamics is useful to anyone trying to extricate themself from the controlling behavior of another person and deal with their own compulsions to do things that are uncomfortable, undesirable, burdensome, or self-sacrificing for others.
The mainstay of management of borderline personality disorder is various forms of psychotherapy with medications being found to be of little use.

Borderline personality disorder (BPD) is a personality disorder characterized by a pervasive, long-term pattern of significant interpersonal relationship instability, a distorted sense of self, and intense emotional responses, which can be misdiagnosed. Misdiagnosis may involve erroneously assigning a BPD diagnosis to individuals not meeting the specific criteria or attributing an incorrect alternate diagnosis in cases where BPD is the accurate condition.
