How a Narcissist Becomes a Narcissist & Why Their Story Doesn’t Excuse Your Scars

Understanding the roots doesn’t excuse the damage, but it explains everything. The pain that started it all.

I didn’t just study narcissism, I lived it.

I was born to a narcissistic mother who saw me as an extension of herself, not a child with my own voice.

I dated a narcissist who twisted my emotions so well that I didn’t even realize it was abuse until I was in therapy.

My sister? Narcissistic too. We haven’t spoken in years after a brutal fallout that exposed just how far she’d go to compete with me and tear me down.

But the worst hit came when I was pregnant with my son. My mother’s younger sister, another narcissist in the family tree, stole a large sum of money from me.

I almost went broke before giving birth. Thankfully, I got it back. But the betrayal? It left a scar.

So when I say this isn’t just theory… believe me, it’s personal.

Why Can’t Narcissists Handle Criticism?

Living with my toxic mother taught me this early: narcissists explode when you challenge them.

Even a simple question like, “Why did you say that?” would lead to hours of emotional warfare.

Dr. Ramani Durvasula describes this perfectly. She says narcissists live in fear of being exposed. That’s why even the smallest critique feels like a personal attack.

It’s not about what you said, it’s about their internal chaos being threatened.

Their entire identity is a performance. Any threat to it? Feels like life or death.

How Does Someone Become a Narcissist?

This part helped me forgive myself for staying too long with the wrong people.

Not them, but me. I realized their behavior was rooted in something they had never dealt with.

1. Early Trauma & Emotional Wounds

Some narcissists are shaped by chaos. Abuse, loss, or neglect. They build a fantasy self to survive. A version of themselves that’s untouchable, powerful, admired.

It’s not real. But it keeps them safe.

2. Conditional Love & Emotional Neglect

Others only received love when they were performing. When they were good enough. When they did what their parents wanted.

Real, safe love? That wasn’t in their vocabulary. So they learned to become what others needed, never who they actually were.

Psychologist Heinz Kohut talked about this. He said that when kids don’t get emotional mirroring, they struggle to develop a stable identity. So, instead, they grow up chasing validation to feel like they exist.

3. Overvaluation & Excessive Praise

Then, there’s the opposite. Some narcissists were worshipped by their parents. Told they were better than everyone else. That they deserved more.

But no one taught them emotional responsibility. No one said, “You’re not better… you’re just human, and that’s enough.”

So they grew up believing the world owed them something.

4. Praise, Punishment Rollercoasters

This one hits hard.

Many narcissists grow up being praised one day and punished the next. One minute, they’re adored. The next, they’re ignored, blamed, or mocked.

My narcissistic mother was like that. If I succeeded, she’d bask in the spotlight like it was hers. If I failed or disagreed with her? The silent treatment, guilt trips, or rage.

That hot-and-cold cycle wires a child to chase approval. It teaches them that love is conditional and that they have to perform for it.

5. Temperament & Genetics

Not every narcissist had a traumatic childhood. Some just had the perfect storm: a sensitive or reactive personality, paired with toxic parenting.

Dr. Ramani notes that a difficult temperament is a risk factor. That doesn’t mean a child is doomed, but it means they’ll be more affected by their environment.

Some kids adapt by becoming people pleasers. Others? They build walls, masks, and egos.

Myth: “They Love Themselves Too Much”

No, they don’t.

Narcissists don’t have real self-love. What they have is a hollow performance of superiority that masks deep self-loathing.

They need constant attention, praise, and control. Not because they feel worthy, but because deep down, they feel like nothing.

The therapist behind GoodTherapy.org put it best: “An inner core of insecurity often lies behind this mask.”

It’s like a black hole of shame they’re always trying to fill, often at your expense.

Myth: “They Just Got Spoiled”

Sometimes, yes. But many times? They were emotionally starved.

Some were praised too much. Others were neglected or torn apart.

The result is the same: They grow up without a grounded sense of self. They rely on admiration, power, and control to feel like they matter.

And in that process, they destroy everyone around them.

Understanding Isn’t Excusing Their Sh*tty Behaviour

I used to think that if I just understood them better, if I loved harder, showed more patience, they would change.

That if I became the perfect daughter, the perfect partner, the perfect sister… they’d finally see me.

But here’s what I learned: You can understand where someone came from and still walk away from who they’ve become.

You can acknowledge their pain and still protect your peace. You can have empathy and still enforce boundaries.

Narcissists Make a Choice to be Bad People

If you’re reading this and thinking, This is my mom. My ex. My sibling. You’re not alone. You’re not crazy. You’re not weak.

You were conditioned to tolerate the intolerable.

The truth? You’ll never change a narcissist. But you can change your story.

And it starts by knowing this wasn’t your fault.
