You've watched someone in your life hold everything together with unsettling control. Nothing cracks the surface. Then something shifts. Maybe they didn't get the promotion. Maybe a relationship ended on someone else's terms. Maybe they were called out publicly, and the person who seemed bulletproof suddenly isn't.
What you're witnessing may be a narcissistic collapse, which is the psychological breakdown that happens when a narcissist's inflated self-image can no longer be sustained.
This post focuses specifically on what causes it. If you've already read our overview of what narcissistic collapse is and how long it lasts, this goes one layer deeper: the specific events and dynamics that actually trigger the breakdown. Understanding the triggers can help you make sense of a reaction that feels completely disproportionate. It can also help you recognize when someone around you is close to collapsing, and if needed, prepare yourself accordingly.
