When your brain senses danger, it doesn’t wait for your permission. It makes a split-second call to keep you alive. That reaction is automatic. Let me say that again. You don’t choose your survival response. It’s not weakness, overreaction, or “losing control.” It’s your nervous system doing exactly what it was designed to do.
This automatic reaction comes from the amygdala (your brain’s alarm center) and the brain stem (your autopilot). They work together like a security system on overdrive. When something feels unsafe, the brain floods your body with adrenaline and cortisol (stress hormones) that crank up your heart rate, sharpen your senses, and get you ready for action or protection.
These survival responses are most commonly known as fight, flight, freeze, or fawn.
Let’s break each one down
Fight: Survival Looks Like Anger
When the brain believes it can overpower a threat, it flips the fight switch. The amygdala sees danger and sends the message: “Push back or you’ll get hurt.”
This can look like:
- Quick temper or irritability
- Defensive body language
- Feeling “on guard” or the urge to prove yourself
- Urge to yell, argue, or physically lash out
Flight: Surviving Means Escape
This can look like:
- Feeling trapped or needing to leave suddenly
- Panic or racing thoughts
- Trouble sitting still
- Always scanning for exits or escape routes
Freeze: Surviving by Shutting Down
This might look like:
- Going blank or zoning out
- Feeling disconnected from your body
- Trouble speaking or moving
- Feeling numb, foggy, or “not really there”
Fawn: Survival Means Being The Peacemaker
If fighting, fleeing, or freezing all feel dangerous, the brain may choose submission. You go along to get along, because safety sometimes means keeping the peace.
This is more often than not a learned behavior. In many traumatic environments (especially childhood abuse or long-term coercion) resistance wasn’t an option. The brain learned that safety came from keeping others calm or happy.
This can look like:
- People-pleasing to avoid conflict
- Difficulty setting boundaries
- Changing your behavior to be accepted
- Saying “yes” when you want to say “no”
You Didn’t Choose This
After trauma, we often blame ourselves: “I should have fought back. I should have stayed calm. I should have run.” This self-judgment comes from our thinking brain critiquing decisions our survival brain made in microseconds. The reality? During trauma, your body chooses for you. Understanding this transforms “What’s wrong with me?” into “My brain was protecting me the only way it knew how.” The truth is simple. There is nothing wrong with you. Your body did exactly what it was built to do. It kept you alive.
