Narcissistic Personality Disorder
TeenThreads Guide: Narcissistic Personality Disorder (NPD) in Teens & School‑Age Kids
“Confidence is healthy. Cruelty isn’t. And real strength is learning how to connect, not control.”
Narcissistic Personality Disorder (NPD) is one of the most misunderstood mental health conditions. People throw around the word “narcissist” like it’s an insult—“He’s such a narcissist,” “She only cares about herself,” “They’re obsessed with attention.”
But the truth is way more complex.
NPD is not about selfies, popularity, or liking your own outfit.
It’s a mental health condition involving deep insecurity, fragile self‑esteem, and patterns of behavior that can hurt the person and the people around them.
This guide breaks it down in a way that makes sense for teens, educators, and families.
1. What Narcissistic Personality Disorder Actually Is
NPD is a long‑term pattern of:
- Needing admiration
- Struggling with empathy
- Feeling superior or “special”
- Being extremely sensitive to criticism
- Having unstable self‑esteem
- Wanting control in relationships
It’s not about being “full of yourself.”
It’s about having a fragile inner world that gets protected by acting confident, powerful, or untouchable.
Think of it like this:
“Outside: I’m amazing.
Inside: I’m terrified of not being enough.”
