How Trauma Rewires Your Brain

You know how people say life has a "before" and "after"? Like before you discovered coffee was actually good (not just bitter brown water), and after you became that person who can't function before their morning cup? Or before you learned what taxes were, and after you lost all innocence?

Well, for me, that line in the sand was drawn when I was nine years old. And spoiler alert: it wasn't about coffee or taxes.

So get comfy for this one: maybe grab that coffee I just mentioned: because we're going back to a normal Sunday that turned into anything but.

The Day Everything Changed

It all started with my family heading to church in the morning, then taking a short road trip to the farm. Everything was calm: laughter, soft conversations, the kind of peace that makes you feel like nothing could ever go wrong. You know those days where life just feels... easy? It really was a great day.

Until the drive back home.

The air still smelled of greenery and open fields, that fresh countryside scent of soil, grass, and wind. The last thing I remember was drifting to sleep as the car rocked gently along the road.

Then: BANG!
A loud crash. Tires screeching. Metal crunching against metal. My mom screaming. The shock jolted me awake, and suddenly I was being thrown around inside the car. Everything was spinning, violent and chaotic. I remember seeing my body moving, feeling the impact, but it all happened so fast there was no time to understand what was real.

When the car finally stopped, everything went silent. Then blank.

When Survival Becomes the Story

When strangers pulled me out of the wreckage, their faces blurred by shock and dust, someone wrapped me in cloth to stop the bleeding and sat me by the roadside. I watched everything in silence, frozen. Eventually, a man: whose kindness still feels sacred to me: offered to drive us to the hospital.

Hours later, I woke up in a hospital bed surrounded by people. I could feel their worry, their fear, their relief all crashing into me at once. The doctors said it was a miracle I survived. Hours in surgery. Countless stitches. A recovery journey that was just beginning.

But here's what no one tells you about miracles: they don't erase the damage. They just give you a chance to carry it differently.

The first time I saw myself in the mirror, I was wrapped in a big head bandage, half bald (they'd shaved my head for surgery) with stitches running across my head and face. My 9 year old self was convinced I looked like a monster. The nurses tried to comfort me, but I couldn't hear them. I just stared at this stranger looking back at me and didn't recognize her.

That girl in the mirror? She wasn't the bubbly kid who raised her hand in class and talked everyone's ear off. She was someone new. Someone quieter. Someone scared.

I didn't know it then, but my brain had already started rewriting itself.

The Invisible Rewiring

Back then, I didn't have words for what was happening. I just knew I wasn't the same. The happy, confident kid disappeared, and in her place was a shell: someone who looked like me but felt hollow inside. I stopped raising my hand in class. Stopped talking as much. Started shrinking into the back of the room, hoping no one would notice me.

I felt ugly. Damaged. And somewhere deep inside, my brain decided that if I could just be good enough: if I could please everyone, prove I was still worthy despite how broken I felt: maybe I'd be safe again.

That's people-pleasing born from trauma. It's not kindness. It's survival.

And here's the thing: I lived like that for years. Numb. Dissociated. Going through the motions of life but not really feeling any of it. I'd smile when people expected it, laugh when it seemed appropriate, but inside? Nothing. I was performing emotions, not experiencing them.

It wasn't until university: when I left home, changed scenery, made new friends, and started creating a life that felt like mine instead of one I was just placed into: that I began to wake up. Slowly, I started feeling again. Not just showing emotions, but actually feeling them. Laughing because something was genuinely funny. Getting excited because I wanted to, not because I should.

That's when I realized: the happy child had been missing for years. I'd been living with undiagnosed depression, walking around like a ghost in my own life.

But why? Why did one traumatic event turn me into a completely different person?

Because my brain, in its desperate attempt to keep me alive, had slipped in through a backdoor and rewired everything without asking. A quick science lesson:

What Trauma Does to Your Brain (And Why You're Not Broken)

Here's what happens when something terrifying shakes your world:

The Amygdala (Your Alarm System) goes into overdrive. Think of it like a smoke detector that got so sensitive after one real fire that now it screams every time you make toast. After my accident, my brain learned that the world wasn't safe: so it stayed on high alert, scanning for danger everywhere, even when there was none.

The Hippocampus (Your Memory Keeper) is supposed to help you file memories away properly, labeling them with "this happened in the past." But trauma can shrink it or mess with how it works. Suddenly, your brain can't tell the difference between then and now. You're not reliving a memory: your body thinks the danger is happening right now. That's why triggers feel so real, even years later.

The Prefrontal Cortex (Your Voice of Reason) is the part of your brain that helps you think clearly, plan ahead, and calm yourself down. It's supposed to tell the amygdala, "Hey, we're okay. That loud noise was just a car door, not another crash." But trauma weakens that connection. The rational voice gets quieter. The fear voice gets louder.

This isn't weakness. This isn't a character flaw. This is your brain trying to protect you the only way it knows how.

The problem is, those protection mechanisms: the hypervigilance, the numbness, the people-pleasing: become their own prisons.

What Trauma Rewiring Actually Looks Like in Your Life

When your brain rewires itself for survival, it doesn't just affect big, obvious things. It seeps into your everyday habits, your relationships, your sense of self. And often, you don't even realize it's happening.

Here's what trauma can look like when it's quietly running the show:

• Procrastination: Your brain sees even simple tasks as potential danger because the alarm system is stuck on high alert. So it avoids. It's not laziness: it's your brain trying to protect you from feeling overwhelmed.
• Imposter syndrome: That nagging voice saying "I'm not enough" often comes from trauma wiring you to constantly scan for flaws and brace for rejection. You expect to be found out because some part of you still believes you're broken.
• Lack of discipline: Trauma messes with your prefrontal cortex, the part that helps you focus, plan, and follow through. Sticking to routines feels impossible because your brain is too busy preparing for disaster.
• Overthinking: Your brain replays old fears on a loop, running constant "safety drills" even when you're not in danger. It thinks if it can predict every bad outcome, maybe it can prevent them.
• Low motivation: Trauma can dull your brain's reward system, making it harder to feel joy, excitement, or drive. Life feels flat because your brain is conserving energy for survival.
• Perfectionism: If mistakes once led to pain, your brain learns that being flawless feels safer. So you chase an impossible standard, terrified of getting it wrong.
• People-pleasing (the fawn response): You learned that keeping the peace, making others happy, and staying small sometimes meant staying safe. So you put everyone else's needs above your own, hoping that if you're good enough, nothing bad will happen.
• Emotional numbness: When feelings get too overwhelming, your brain just shuts them down. You go through life on autopilot, disconnected from yourself, because feeling nothing is safer than feeling everything.
• Explosive anger: The alarm center reacts in a flash while the calming part of your brain struggles to hit the brakes. You snap at people over small things because your body is still reacting to old, unresolved danger.
• Difficulty trusting: Trauma blurs the line between past and present, so even when new people are safe, your brain keeps waiting for the other shoe to drop.
• Sleep problems: Your body feels like it's on guard duty 24/7, so it resists fully relaxing. Even at night, some part of you is still watching, waiting, protecting.
• Addiction and substance use: Here's what people don't talk about enough: when your brain is constantly stuck in survival mode, it's exhausting. You're hypervigilant, replaying painful memories, feeling things too intensely or not feeling them at all. So your brain starts searching for relief: something, anything, to turn down the volume on all that noise.

That's where addiction can slip in. Whether it's alcohol, drugs, food, sex, shopping, endless scrolling on social media, or even work: these become ways to self-medicate the pain your brain doesn't know how to process. It's not weakness or lack of willpower. Your traumatized brain learned that certain behaviors or substances provide temporary escape from the constant alarm bells ringing inside.

None of this makes you broken. It makes you human. It makes you someone whose brain did exactly what it was designed to do: survive.

But survival mode was never meant to be permanent.

There Is Hope: Your Brain Can Change

Truth is trauma leaves fingerprints on your brain, but it doesn't get the final say.

Thanks to something called neuroplasticity, your brain can rewire, reshape, and relearn. It can build new pathways. It can remember what safety feels like. It can learn to trust again, to feel again, to live again: not just survive.

“Be transformed by the renewing of your mind.” — Romans 12:2

This isn't just wishful thinking. It's science meeting spirit. It's the reality I've lived and the work I do every day.

Through my coaching, I help people notice where trauma loops are silently running the show: whether it's procrastination, self-doubt, numbness, people-pleasing, or addiction: and then guide them into practical tools and faith-based strategies to rewire those patterns.

Think of it as having someone who not only understands the science but has walked through the storm herself, walking beside you as you learn how to reclaim your mind.

You don't have to keep living from that nine-year-old's fear. You don't have to keep performing emotions you don't feel or shrinking yourself to feel safe. You don't have to stay numb.

There's a version of you on the other side of this healing: one who feels alive, confident, and free. One who creates the life they want instead of just surviving the one they're in.

And I'd love to help you find your way there.
