Matthew Sexton, LCSW · NATC — Nassau County, NYC & Telehealth
Therapy for Narcissistic Abuse & Antagonistic Relationships
You're not oversensitive. What happened to you was real.
Recovery from narcissistic abuse requires more than general trauma therapy. It requires a clinician who understands the specific mechanisms of coercive control, identity erosion, and the psychological aftermath of antagonistic relationships.

Specialized Certification
Certified Narcissistic Abuse Treatment Clinician (NATC)
Matthew Sexton holds the NATC credential — Certified Narcissistic Abuse Treatment Clinician — a specialized certification in the assessment and treatment of narcissistic abuse and antagonistic relationship dynamics.
Most therapists are trained in general trauma or couples work. The NATC credential means Matthew has undergone specific training in the mechanisms of narcissistic abuse — the patterns, the aftermath, and the clinical protocols for recovery. You don't need to spend sessions explaining what DARVO is or why you stayed.
“Narcissistic abuse leaves a very specific kind of damage — to identity, to reality orientation, to the capacity to trust yourself. That requires very specific clinical work.”
Understanding What Happened
Patterns of Narcissistic Abuse
Naming the patterns is often the first step. These dynamics are deliberate, systematic, and leave a predictable clinical footprint.
Gaslighting
Persistent reality distortion — making you doubt your memory, perception, and judgment — until you no longer trust your own experience. One of the most psychologically damaging forms of manipulation.
Love Bombing & Idealization
Intense early affection, attention, and idealization that creates a powerful attachment — then is systematically withdrawn or made conditional to establish control.
Coercive Control
A pattern of behavior used to dominate and control — restricting autonomy, monitoring movements, undermining relationships, and using emotional leverage to maintain power.
Devaluation & Discard
After idealization, a systematic dismantling of your self-worth — criticism, comparison, contempt — followed by abandonment or threat of abandonment as a control mechanism.
DARVO
Deny, Attack, Reverse Victim and Offender. A predictable defensive response that leaves victims feeling responsible for the harm done to them — and doubting whether harm occurred at all.
Flying Monkeys & Triangulation
Using third parties — mutual friends, family members, colleagues — to gather information, spread narratives, or apply social pressure. Isolation and reputation damage are common consequences.
The Clinical Work
What Recovery Actually Involves
Validate Your Reality
Narcissistic abuse systematically distorts perception. Recovery begins with establishing what actually happened — rebuilding a reliable internal reality that was deliberately undermined.
Process Complex Trauma
Relationships with narcissistic or antagonistic partners create complex PTSD — not a single traumatic event, but accumulated relational trauma that requires specialized clinical processing.
Reconstruct Self-Concept
Prolonged exposure to devaluation and gaslighting erodes identity. Therapy rebuilds a coherent, accurate sense of self that isn't organized around another person's distorted projections.
Rebuild Relational Safety
Antagonistic relationships recalibrate how you relate to others — triggering hypervigilance, fawn responses, or avoidance. Therapy restores the capacity for genuine connection with appropriate discernment.
Who This Practice Serves
Antagonistic Relationships of All Kinds
Narcissistic abuse doesn't only happen in romantic partnerships. It occurs in family systems, workplaces, and friendships — and the psychological aftermath is similar regardless of the relationship type.
