Narcissist or schizophrenic or both?

5. Paranoia can be part of narcissistic collapse

Surveillance

When a person high in covert narcissistic traits enters collapse, their internal world shifts from quiet superiority to distrust, abandonment terror, and desperation to feel relevant.2,3 They can collapse inward into a state of paranoia, hypervigilance, and catastrophic fear of losing their primary source of validation, triggering fears of being forgotten. This free-fall can produce a sudden switch from avoidant behavior to a pattern of compulsive behavior.

The same person who once withdrew, stonewalled, or acted passive-aggressively may now shift into obsessively thinking about their lost "supply" and covertly monitoring them with late‑night emails, “baiting” and triangulation attempts, mysterious burner phone calls, or “accidental” attempts to bump into them when running errands or out with friends. These behaviors are designed to regain narrative control and emotional dominance, not emotional connection. It is important to recognize that their obsessiveness is not about love, closure, or providing an apology, but possessiveness, sadistic intensity, and a compulsion to reclaim what they have lost.
