Why Are You So Tired After Leaving a Narcissist?

So, you’ve finally broken free from the chaos of a narcissistic relationship. You’re free! You can breathe, snack without judgment, and wear whatever you like without someone making it about them.

But instead of dancing around in victory, you feel…tired. Not the kind of tiredness that a cup of coffee will fix, but the deep, bone-weary kind that makes you want to hibernate for a month. If you’re wondering why, let me assure you, it’s not all in your head.

I get it, I’ve been there too and it’s very normal to feel this way after leaving a narcissist behind.

In my own life, my toxic mother was a master manipulator, always charming the rest of the family while quietly tearing me down behind closed doors. Despite cutting ties with her, I remember how drained I felt afterward as if I had run a marathon without ever moving.

Turns out, this exhaustion is completely normal. After years of stress, your body and mind need to recover, and it’s not an overnight process.

KEY TAKEAWAYS
  • Leaving a narcissist is mentally, emotionally, and physically exhausting because your body has been stuck in survival mode for years.
  • The fatigue you feel after leaving a narcissist is a natural part of the healing process as your body finally releases built-up tension and stress.
  • Triggers, such as hearing from the narcissist or reliving old memories, can temporarily set back your recovery, but recognizing them helps you stay on track.

Why Am I So Exhausted After Leaving a Narcissist?

After leaving a narcissist, your body and mind go through a bit of a detox. And no, we’re not talking about some juice cleanses, this is a full-on “release the tension you’ve been holding for years” kind of thing.

You’ve been in survival mode for so long that your nervous system is in disarray, and it’s normal to feel absolutely drained.

Here’s why you’re so tired (and no, it’s not just because you binged Netflix to cope).

1. The Mental Load Was Overwhelming (A Constant State of Alert)

Living with a narcissist, whether it’s a partner, friend, or, in my case, a family member, is like walking through a minefield, you never know when the next explosion is coming.

My mom could be sweet and charming one minute, only to turn the entire family against me the next. I remember the emotional exhaustion of always having to second-guess her motives and actions.

You likely spent most of your time trying to avoid conflict, always on high alert. That constant state of mental tension is incredibly draining. It’s no wonder that now when you’re finally out, your brain feels like it’s been put through a blender.

This mental exhaustion takes a serious toll:

  • Walking on eggshells: You were always tiptoeing around their mood swings, trying to avoid setting them off.
  • Mental gymnastics: Constantly figuring out how to navigate their manipulation tactics left you mentally fried.

2. Your Nervous System is Trying to Recalibrate (The Fight, Flight, Freeze Hangover)

For years, you’ve been stuck in fight, flight, or freeze mode. Your body has been primed for danger at every turn. When you’re constantly in that heightened state of stress, your body eventually forgets how to relax.

Growing up with a mother who made me feel like I was always on trial, criticizing my looks, intelligence, and achievements—my nervous system never caught a break. Even after I cut her off, my body took months, even years, to adjust to not being in “danger mode” anymore.

Here’s why this leaves you feeling so drained:

  • Fight or flight overdrive: Your body was in constant battle mode, and now it’s exhausted.
  • Cortisol crashes: Your stress hormones have been in overdrive for so long, and now they’re crashing hard, leaving you feeling physically and emotionally drained.

3. Coping Mechanisms Wore You Down

The strategies you developed to survive living with a narcissist whether it was fawning (people-pleasing) or freezing to avoid confrontation—took a serious toll on your mental and emotional well-being.

My sister, who used to be my confidant, became someone who tried to tear me down once I succeeded. I found myself constantly freezing in her presence, unable to defend myself for fear of further backlash.

Now that you’re out of that toxic environment, your body doesn’t need these mechanisms anymore. But the exhaustion from constantly using them has left you feeling depleted.

Here’s how they contributed to your fatigue:

  • Freezing: You may have often felt stuck, unable to act or speak up for yourself.
  • Fawning: Pleasing the narcissist, just to avoid drama, wore you out.

4. Healing Takes Time (and It’s Okay to Take it Slow)

The exhaustion you feel isn’t a sign of weakness, it’s your body’s way of telling you it needs time to heal. Healing from narcissistic abuse isn’t linear, and it’s certainly not quick.

Growing up in a household where my mom’s manipulation was constant, it took years for me to stop feeling guilty and tired after cutting ties with her. I expected instant relief, but that’s not how it works.

While you may want to feel better instantly, the exhaustion is actually a sign of healing, and here’s why it’s crucial to take things slowly:

  • It’s a marathon, not a sprint: Your energy will come back, but it’s going to take time.
  • Be kind to yourself: The recovery process isn’t about doing more, but about letting yourself rest. You’re healing from deep wounds.

5. The Mental and Emotional Toll (It Wasn’t Just Your Body)

Living with a narcissist isn’t just about dealing with their verbal abuse, it’s the emotional manipulation that really takes a toll.

In my case, my sister, once a close ally, started spreading lies about me to our family and friends. It was mentally and emotionally draining, constantly trying to defend myself or understand why she was behaving that way.

The emotional and mental gymnastics required to navigate a narcissist’s manipulation leave lasting effects, and here’s how they drain your energy:

  • Gaslighting: Narcissists are masters at making you question your reality. That kind of manipulation wears you down over time.
  • Emotional labor: Just trying to make sense of the constant manipulation and drama takes a huge toll on your mental health.

6. Being in Survival Mode for Too Long (High Alert All the Time)

When you’re with a narcissist, your body and mind are stuck in survival mode. Whether it was avoiding your narcissistic mother’s sharp words or dealing with manipulative siblings, you were always bracing yourself for the next emotional hit.

When I was still with my narcissistic family, I spent a lot of time alone, teaching myself to be independent because I couldn’t rely on them for support.

Even now, it can feel strange to be out of survival mode, and your body’s response is often exhausted. It’s like getting off a roller coaster, you’re still wobbly and disoriented.

Here’s why that contributes to the fatigue you feel now:

  • High alert mode: Your body was always ready to defend itself, which left you emotionally and physically drained.
  • The rollercoaster effect: Once you’re out, your body still needs time to adjust and trust that the danger is gone.

What Are Common Triggers That Can Set Back Your Recovery?

The road to healing isn’t always a straight line. There will be triggers that can unexpectedly bring up old emotions and make you feel like you’re back to square one.

For me, hearing about my sister or mother through family members can sometimes bring up those old feelings of doubt or anger, even though I’ve come a long way in my healing.

Here are a few triggers to watch out for:

  • Hearing from the narcissist: Even a simple text or message can send you spiraling. In my case, a message from my mother would instantly throw me back into old patterns of guilt.
  • Seeing or hearing about them: Social media posts or conversations about them can bring up unresolved emotions. This is why I’ve muted and blocked all contact with my mother and sister.
  • Anniversaries or significant dates: Birthdays or holidays can bring up memories of the toxic relationship, triggering sadness or anger.
  • Dreams or flashbacks: Sometimes, even after years, I still have flashbacks to moments where I was hurt by my family. It’s your mind’s way of processing trauma, but it can feel like a setback.

These triggers are a normal part of recovery. The key is to recognize them and have strategies in place to handle them.
