Borderline Personality Disorder (BPD) is better understood as a form of complex post-traumatic stress, rooted in chronic relational trauma and emotional neglect rather than a fixed “personality flaw.” The term itself emerged from outdated psychoanalytic theory, describing people as being “on the border” between neurosis and psychosis, a label that pathologised emotional intensity and distress rather than contextualising it. Many clinicians now recognise the diagnosis as both stigmatising and gendered, historically applied disproportionately to women whose pain was misunderstood or minimised. A trauma-informed understanding reframes BPD as a survival response to overwhelming relational injury, not a defect of character.

We understand Borderline Personality Disorder as a trauma-related condition shaped by disrupted attachment, chronic threat activation, and difficulties in emotional regulation. The mechanisms involve a sensitised nervous system, responding to ‘the threat was also the primary attachment’ dynamic, internalised shame, and schemas formed around abandonment, mistrust, and defectiveness.

In therapy, I work to build safety and coherence through a combination of schema therapy (to identify and heal core beliefs and modes), somatic and polyvagal approaches (to regulate the body’s threat responses), and relational repair, offering consistent attunement to help the client internalise a sense of stability, worth, and self-compassion. BPD can show up in some of these ways:

All therapy begins with ESTABLISHING SAFETY. This is an ongoing process in therapy. Alongside this, we’ll do what’s call a ‘complex assessment’. A complex assessment is just a really intrusive conversation that’s like a diagnostic scan: we take time to look under the hood of what’s happening with your mind, emotions, relationships, and life context. It means I ask more questions, look for patterns, gather different data, and aim to create a map (a formulation) of how all the parts of your experience fit together. The goal is not just to label, but to understand, so that whatever therapy we do, it’s better-tailored and more likely to help.

A complex assessment might have this kind of format:

• Extended interview & history
  I’ll spend more time asking about your life history, early experiences, relationships, significant events, medical history, and patterns over time (not just what brought you in now).

• Multiple sources
  I might ask for permission to speak with (or review reports from) others who know you (e.g. GPs, previous therapists), or look at past medical or psychological records (with your consent).

• Use of tools / measures
  Schema questionnaires, symptom inventories, risk screening (e.g., self-harm or safety) may be used to give us structured data.

• Contextual exploration
  I’ll look at your environment, cultural background, current stresses (work, family), social supports, and systemic factors (financial, social, health) that influence your struggles.

• Hypothesis / formulation building
  Rather than just saying “you have anxiety or depression,” I build a “story” or “map” of how these themes developed, what’s maintaining them, and where change might happen.

• Planning & recommendation
  The output is not just “you’re this diagnosis,” but a plan: what kinds of therapy may help, in what order or priority, what risks to watch, and what supports you’ll need. It means we agree on a shared understanding of what the ‘problem’ is, and we might not be able to address everything, but that’s not what therapy is for. What we can do is see where there’s scope to grow, evolve, unstick the stuck and transform, something.

To this end, each therapeutic plan is different and tailored to your needs, and we tweak as we go depending on your changing needs. Essentially though, our relationship is the primary tool and strategies we explore within help keep us focused.
