Borderline Personality Disorder (BPD) in Singapore

Written & reviewed by the BestDoctors.sg editorial team · Last updated 1 Sep 2026 · General information, not medical advice

BPD is one of the most stigmatised and misunderstood conditions – yet also one where the outlook, with the right therapy, is genuinely hopeful. The behaviours that look “difficult” from the outside are usually attempts to cope with overwhelming pain.

What it is

Borderline personality disorder is a recognised mental-health condition that affects how a person manages their emotions and how they experience relationships and their own identity. People living with BPD tend to feel emotions very intensely – joy, hurt, anger and fear can all arrive with great force – and find those emotions difficult to regulate or settle once they have been triggered. The alternative name, emotionally unstable personality disorder, captures this emotion-regulation core: the underlying difficulty is not a flaw in someone’s character but a genuine struggle to steady feelings that swing quickly and powerfully.

It helps to think of BPD as a condition that shapes a person’s inner world rather than defining who they are. Many people carry it quietly, holding down work, study and friendships while battling storms that others cannot see. Crucially, BPD is treatable. It is not a life sentence, and it does not mean a person is broken or beyond help. With the right therapy and support, the intensity of symptoms tends to ease, and a great many people go on to build stable, meaningful lives. Recovery is realistic, and it is worth holding on to that hope.

Symptoms

BPD shows itself in several patterns, and not everyone experiences all of them or to the same degree. The main features usually group as follows:

• Intense, rapidly changing emotions. Moods can shift dramatically over hours, and feelings often seem larger and harder to calm than others expect.
• A strong fear of abandonment. A deep dread of being left, rejected or alone, which can drive frantic efforts to keep people close – even when there is no real threat of being abandoned.
• Unstable relationships. Connections can swing between idealising someone (seeing them as perfect) and devaluing them (feeling badly let down), sometimes within a short space of time.
• An unstable sense of self. Uncertainty about who one is, what one values or where one is heading, so that identity, goals and even opinions can feel like they keep shifting.
• Impulsive or risky behaviour. Acting on strong urges – which may involve spending, driving, substance use, disordered eating or other risky acts – often as a way to relieve unbearable tension.
• Chronic feelings of emptiness. A persistent hollow or numb sensation, as though something inside is missing.
• Difficulty trusting others, and sometimes brief episodes of feeling suspicious, disconnected or detached from oneself when stress is high.
• Urges to self-harm or thoughts of suicide. These are common in BPD and must always be taken seriously. They are a sign of deep pain, not attention-seeking, and they deserve compassion and prompt help – never judgement. If these thoughts are present, support is available and reaching out is a sign of strength.

Because these symptoms overlap with everyday emotions, BPD is best recognised by their intensity, their persistence and the toll they take on relationships and daily life rather than by any single experience on its own.

Causes and who is at risk – not the person’s fault

There is no single cause of BPD. Current understanding points to a combination of genetic, brain and life-experience factors that interact with one another. BPD can run in families, suggesting an inherited vulnerability, and differences in how the brain processes emotions may make feelings harder to regulate. On top of this, many – though not all – people who develop BPD have lived through childhood adversity, such as trauma, neglect, loss, or growing up in an environment where their feelings were dismissed or invalidated.

It is important to be clear that having BPD is not the person’s fault, and it is not caused by weakness, poor upbringing on the individual’s part, or a lack of willpower. It is best understood as an understandable response to a vulnerable temperament meeting painful early experiences. Understanding the roots of BPD is not about assigning blame – it is about opening the door to compassion and effective treatment.

How it is diagnosed

BPD is diagnosed by a mental-health professional, such as a psychiatrist or clinical psychologist, through careful assessment over time rather than from a single test or a one-off appointment. The clinician will explore a person’s emotions, relationships, self-image and behaviour patterns, usually across more than one conversation, to build a full and accurate picture. A trusting, unhurried assessment matters, because the goal is to understand the whole person, not to attach a label.

BPD frequently overlaps with other conditions, including depression, anxiety, post-traumatic stress disorder (PTSD), eating difficulties and substance-use problems. These can share or mask symptoms, which is one reason a careful, professional assessment is so valuable. Identifying any co-existing conditions is helpful, because it allows treatment to address everything a person is dealing with, together.

Treatment – hopeful and specific

The outlook for BPD is genuinely encouraging, and treatment is effective for many people. Psychological therapy is the main treatment – talking therapies designed specifically for BPD can help a great deal.

The best known is dialectical behaviour therapy (DBT), a structured approach that teaches practical skills in four areas: mindfulness (noticing the present moment), distress tolerance (getting through crises without making things worse), emotion regulation (understanding and steadying strong feelings) and interpersonal effectiveness (handling relationships and boundaries). Other evidence-based therapies include mentalisation-based therapy (MBT), which strengthens the ability to understand one’s own and others’ mental states, and schema-focused therapy, which works on long-standing patterns rooted in early experiences. Different approaches suit different people, and a clinician can help find the right fit.

Medication is not a main treatment for BPD itself. It is not used to “cure” the condition, but it may sometimes help manage co-existing conditions such as depression or anxiety, or ease particular symptoms for a time. Any medicine should be prescribed and reviewed by a doctor as part of a wider plan centred on therapy.

Treatment takes time, and progress is often gradual rather than instant – but improvement is very possible. With commitment and support, many people with BPD experience fewer and less intense symptoms over the years, and a large number go on to recover. Setbacks along the way are normal and do not undo the progress already made.

Self-help and coping

Alongside professional treatment, small daily practices can make intense emotions more manageable:

• Learning to recognise and ride out intense emotions, reminding oneself that feelings rise and pass like waves, and using grounding or breathing techniques to get through the peak without acting on urges.
• Building routine and structure – regular sleep, meals, movement and gentle activity – which can steady mood and give the day a reassuring shape.
• Nurturing support, whether trusted friends and family, peer-support communities, or a clinician, so that hard moments do not have to be faced alone.
• Having a personalised crisis plan, worked out in advance, that lists warning signs, calming strategies, safe people to contact and the helplines to call. A written plan makes it far easier to reach for help when distress is high.
• Being kind to oneself, avoiding alcohol and drugs as a way to cope, and treating recovery as a marathon rather than a sprint.

Supporting a loved one

Family and friends can make a real difference. What helps most is patience, non-judgemental listening and taking distress seriously – validating that the pain is real, even when the behaviour is hard to understand. Learning about BPD reduces fear and blame on both sides, and gently encouraging professional treatment (rather than pushing) tends to work best. Steady, kind boundaries are not a rejection; they protect the relationship and model stability. Carers should also look after their own wellbeing, seeking their own support so they can keep giving without burning out. Consistency, warmth and hope from the people around them can be a powerful part of someone’s recovery.

When to seek help – and a note on safety

Reaching out is a sign of strength, and recovery is realistic. A GP or polyclinic can be a first step and can refer to mental-health services. In Singapore, support includes the Institute of Mental Health (IMH) and its emergency helpline, the Samaritans of Singapore (SOS) 24-hour hotline on 1767, and the national mindline.sg. Self-harm urges and suicidal thoughts are common in BPD and deserve compassion and help, not judgement – please treat them as a reason to reach out, not to hold back. If someone is in immediate danger of harming themselves, go to A&E or call 995 right away.

Need to talk to someone now? Call the Samaritans of Singapore (SOS) 24-hour hotline on 1767, text CareText on WhatsApp 9151 1767, or call the national mindline on 1771. In an emergency, call 995.
