When you have been abused by a narcissist, it’s not just your heart and mind that carry the scars—your body learns to mirror the trauma, bending under the weight of abuse until it becomes part of who you are, whether you realize it or not. Your posture and body become an extension of your survival mode, and this is often the most overlooked part of the healing journey from narcissistic abuse.
1. You shrink your presence
One of the most noticeable impacts of narcissistic abuse trauma is how it makes you shrink physically, not just emotionally. You carry yourself in ways that suggest you’re trying to hide, to make yourself invisible. You hunch over, close in on yourself, and make your body as small as possible, trying to take up little space. Why? Because you’ve been conditioned to believe that the less noticeable you are, the less likely you’ll be attacked, criticized, humiliated, or abused. It’s a way of avoiding punishment, a survival instinct.
The narcissist made you feel that attention always led to confrontation, so your body adjusts by staying small. Unfortunately, the truth is that this shrinking posture sends signals to others that you are diminished, that you’ve lost power. It’s the first step in physically losing touch with your confidence. I stayed hidden all the time; I didn’t want to be seen because, for me, attention meant pain. I would turn into something small, almost ghost-like in the room, hoping nobody would pay attention to me. I would say nothing, and people assumed I was shy, but it wasn’t shyness—it was fear. Whenever I said something in front of my parent or another narcissist, I was punished for a crime I didn’t commit.
2. The loss of open expression

Over time, you stop being able to express your true feelings when you’re with a narcissist, and your body reflects that. The narcissist trains you to suppress your emotions—whether it’s excitement, anger, joy, or sadness. You quickly learn that any emotional reaction will be used against you. As a result, you become stiff: shoulders tense, lips pressed together, movements controlled. Even after the narcissist is no longer in your life, this behavior persists.
Your body stays locked up, making it harder for you to connect with others and feel free in your own skin. It’s as if your emotions are caged inside, and your body has no outlet to release them. Whether it’s frustration, sadness, or excitement, you keep them hidden because expressing these emotions could trigger the narcissist’s anger or jealousy.
The narcissist weaponizes your vulnerability, making emotional suppression second nature, which can lead to various health issues. Essentially, your brain starts perceiving emotions as enemies—causes for punishment or suffering—and that’s why they get suppressed.
3. Hypervigilance and startle reflex

When you’ve been terrorized by a narcissist, your body never fully relaxes. You’re always ready, waiting for the next attack or insult. Your muscles stay tense, your senses sharp, and even small noises or raised voices trigger a fight-or-flight response.
This hypervigilance is your body’s way of staying prepared for danger, even after the narcissist is gone. Your body clings to past fears, making it difficult to feel truly safe. A simple disagreement or a raised voice can make your muscles tense and your heart race, as if bracing for confrontation.
This physical response, known as a startle reflex, is a residue of the abuse. You were conditioned to expect volatility. I’ve struggled with this trauma response all my life—one sudden noise, and I jump out of my skin. People have asked me, “What’s wrong? It was just a door closing,” but to my nervous system, it felt like the beginning of chaos.
4. Nervous gestures and fidgeting

Many survivors of narcissistic abuse develop nervous habits like fidgeting, biting their nails, or playing with their hair. These repetitive behaviors are your body’s way of channeling the anxiety and fear built up over time. Often, you may not even realize you’re doing it, but these gestures communicate to others that you’re uncomfortable or unsure of yourself.
Living under constant stress with a narcissist creates these nervous habits as coping mechanisms. They’re small signals of unease you carry with you, even when you try to appear calm. In social settings, these nervous tics can make it difficult to feel confident, and others may pick up on your discomfort.
5. Defensive postures and boundaries
Victims of narcissistic abuse often adopt defensive body language, even in neutral situations. You may instinctively cross your arms, keep a physical distance from others, or position yourself near exits. These postures are your body’s way of maintaining a sense of control in environments where you feel you could be targeted.
Because you’ve been conditioned to expect betrayal, confrontation, or manipulation, your body retains the defenses you built during the abuse. Even though the narcissist is no longer a threat, your body still holds onto the idea that it needs protection. These defensive postures create distance between you and others, making connection and trust difficult.
You don’t have a disorder; your personality adapted to survive the incomprehensible. In an environment full of uncertainty, you created extreme responses in your body, brain, and mind just to cope. Now that you’ve survived, it’s time to approach yourself with compassion, because compassion is the first step toward healing.
