Notable Quotes
“If it makes you sick 20 years later, that was not just stress. That was trauma your body was experiencing in childhood. You’re looking at it through the lens of your adult self now, but that’s not how you were experiencing it back then.”
“The critical line of overwhelm is where you’ve done your best. Your best wasn’t good enough, and hitting the wall means there’s no point in trying anymore.”
“Brain inflammation is part of a trauma response. Sometimes it triggers it. Sometimes it’s triggered by the freeze response, but they always happen together.”
“Dysregulation multiplied by time becomes diagnoses. It’s predictable.”
“Track your nervous system, and you’ll be amazed at how much you learn about yourself in a week.”
Episode Takeaway
The critical line of overwhelm represents your personal threshold where stress becomes trauma and your body automatically engages the emergency brake. Brain inflammation during freeze is part of the deliberate survival strategy – helping you disconnect, go numb, and conserve energy for survival. The insight: dysregulation multiplied by time becomes disease. Autoimmunity takes approximately 20 years of compounded nervous system dysregulation to manifest. This explains why short-term stress doesn’t cause chronic illness but prolonged trauma patterns do.
The three-day nervous system journal – tracking your inner state hourly – reveals patterns invisible to both practitioners and clients. This tracking tool shows how much time you spend in each of the three states and guides targeted intervention.
Quality sleep stands as the single most powerful starting point for nervous system regulation. Better sleep reduces emotional eating, decreases sugar cravings, and increases your capacity to handle stress before crossing that critical line into trauma territory.

The Critical Line of Overwhelm: When Stress Becomes Trauma and Your Brain Protects You Through Inflammation
“When did you first have that thought, have that feeling – I don’t know if I’m going to be okay?” This question reveals more about childhood trauma than any diagnostic checklist.
The moment a child questions their own safety marks a threshold where manageable stress transforms into overwhelm and a trauma response for the body.
Most people confuse stress and trauma, using the terms interchangeably. This confusion leads to minimizing genuine trauma experiences while simultaneously shaming yourself for having normal trauma responses. Understanding the difference can change everything about how we approach healing.
When Your Body Feels Like the Enemy
My definition of trauma comes from clinical observation: if an experience makes you sick two decades later, it wasn’t just stress. Autoimmunity, chronic fatigue, persistent anxiety – these conditions don’t arise from temporary stress.
You may look back at childhood events through your adult lens and wonder why they affected you so profoundly. A 6-year-old doesn’t process parental criticism the same way a 30-year-old does.
My working definition of trauma: Anything that, at that time, overwhelmed our ability to understand, process, and respond in a way to overcome.
The key phrase: “at that time.” Your current capacity tells you nothing about what you could handle at age 5, 8, or 12.
When the Body Says “No More”: My Personal Breaking Point
Adopting Miguel from foster care at age 4 taught me this truth viscerally. My love for him terrified him. The more I loved him, the more violently he pushed me away – with aggression, threats, and daily chaos that turned my home into a survival zone.
Child psychiatrists delivered their prognosis: “His future is in jail and on drugs. That’s what you can expect.”
That prediction motivated me to prove them wrong. But the chronic stress pushed my body beyond its capacity. I developed chronic fatigue, autoimmunity, depression and anxiety. I was on two mood medications and was 30 pounds overweight despite my athletic background.
What I still had yet to learn myself: this wasn’t just stress on my body. This was trauma for my body.
The Critical Line of Overwhelm: Your Personal Threshold
Think of driving a self-driving car increasingly fast. At some point, the car’s safety system says “we’re going too fast” and would automatically engage the emergency brake. You don’t choose this. The system overrides your control to prevent catastrophic damage.
Each person has a capacity for stress before crossing into trauma territory. I call this the critical line of overwhelm.
Three distinct nervous system states:
- Calm aliveness – Restorative mode allowing healing, connection, and creativity
- Activation – Fueled by adrenaline for productivity, focus, and hypervigilance
- Shutdown – Emergency brake engaged when activation exceeds capacity
The critical line marks where activation becomes trauma and your body automatically shuts down.
This represents the fundamental difference between stress and trauma. Stress involves power – you’re still trying to overcome challenges. Trauma involves powerlessness – you’ve hit a wall where trying feels pointless.
Hitting the Wall: When Your Best Isn’t Good Enough
Standing in front of my attending surgeon during surgery residency – tall, male, piercing blue eyes representing my father in every triggering way. He was reprimanding me and it sent my body into its memories even though I didn’t want to.
I watched myself go into “little girl mode” in real time: “I can never do anything right. I’m a failure. I am broken and defective.”
The emotional response triggered immediate brain shutdown. I felt it happening – immune cells in my brain unleashing inflammation at that exact moment.
Brain Inflammation as Protective Strategy
Before studying trauma biology, I had no idea emotional triggers could activate immune cells in my brain to unleash inflammation instantly.
Why brain inflammation serves survival:
- Facilitates disconnection from overwhelming reality
- Creates numbness preventing emotional overwhelm
- Stops thinking to conserve precious energy
- Enables survival through dissociation
My body was literally saying: “I’m going to help you not care. I’m going to help you feel paralyzed so I can protect you and maybe we can survive this.”
Brain inflammation isn’t malfunction during trauma – it’s protection. Sometimes it triggers freeze. Sometimes freeze triggers it. But they always happen together.
This understanding provides intervention points:
- Address psychological triggers (authority figures representing father)
- Support brain inflammation through biological interventions
- Increase stress tolerance before inflammation gets triggered
- Complete freeze responses to prevent inflammation cascade
Dysregulation Multiplied by Time Becomes Disease
The formula is predictable: dysregulation × time = diagnoses.
For autoimmunity specifically, research shows approximately 20 years of nervous system dysregulation before symptoms manifest. Short-term dysregulation causes no lasting harm. Your body handles brief activation periods beautifully.
The problem arises when you never return to that restorative operating mode – calm aliveness. When your body never enters repair mode to clear accumulated damage, that damage compounds until it manifests as diagnosable disease.
Biological impacts of chronic dysregulation:
- Mitochondrial function decline reducing cellular energy
- DNA damage from uncleared oxidative stress
- Accumulated inflammation creating tissue damage
- Gut dysfunction affecting neurotransmitter production
The Three-Day Nervous System Journal: Simple Tracking That Transforms
As a practitioner, I needed to know where clients’ internal states actually resided versus where they thought they were. The three-day nervous system journal solved this elegantly.
How it works:
- Print a sheet showing the three states (parasympathetic, stress, shutdown)
- Every hour while awake, mark where your nervous system is
- Don’t analyze or judge – just mark the sheet
- Continue for three full days
Single days don’t reveal patterns. Three days can show the consistent reality of your nervous system’s default operating mode.
Track your nervous system for one week and you’ll be amazed at what you learn about yourself.
The Body’s Innate Healing Intelligence
Surgery residency taught me: the body knows how to heal itself when given proper conditions.
I would perform surgery, make an incision, and – provided clean skin and dry field – the body healed itself. I didn’t need to do extra steps. The body’s innate healing mechanisms activate automatically.
This reveals:
- Your body possesses inherent healing capacity
- Healing happens automatically with right conditions
- If healing hasn’t occurred, something blocks the process
- Remove blocks rather than forcing healing
Instead of trying to heal people, I focus on identifying and removing what blocks their innate healing capacity.
Three Categories of Repair Tools
Parts work repairs fragmentation: Young parts still stuck in traumatic moments need integration through compassionate recognition and reparenting.
Somatic work repairs incomplete responses: Movements frozen during threat need completion – the protective actions, speaking up, or physical boundaries never established.
Biology work repairs cellular damage: Brain inflammation, gut imbalances, mitochondrial dysfunction, and hormonal dysregulation need targeted interventions.
That young Aimie standing ashamed in front of her father needs parts work. The freeze responses need somatic completion. The brain inflammation and gut dysfunction need biological intervention.
The Gut-Brain Connection: Understanding the Loop
Research calls the gut our “second brain.” Some researchers go further: the gut is our primary brain.
My gut was completely imbalanced – leaky gut, bacterial overgrowth, stomach acid problems, food sensitivities. I’d ignored my body for years.
Key neurochemicals affected by gut health:
- Serotonin (85% produced in the gut)
- Dopamine (requires proper gut function)
- GABA (calming neurotransmitter)
These aren’t just for mood – they affect energy, pain perception, immune function, and stress tolerance.
The biology of trauma® loop: Gut imbalance creates neurochemical problems → neurochemical problems create brain inflammation → brain inflammation worsens gut function → cycle continues without intervention.
This loop dramatically impacts capacity for trauma therapy. You might lack energy for good therapeutic work or shut down before processing begins.
Food’s Hidden Functions: Beyond Willpower
I had to ask myself: What do I use food for?
What I discovered:
- Using food to stay awake when exhausted
- Reaching for quick energy to push through fatigue
- Selecting foods for immediate activation
- Timing caffeine for maximum effect
After deep therapy sessions, I’d come home unable to stop eating. “What the heck is going on?”
The deeper question revealed patterns: Why am I eating this particular food right now? What feeling am I trying to avoid?
So much of my eating served to numb grief. I wanted to focus on work, not feel emotions surfacing from my body.
Your body can generate hunger signals even when you’re not physically hungry. This isn’t a willpower problem – it’s a nervous system regulation problem manifesting through food relationships.
The Single Most Important Starting Point: Quality Sleep
If someone could only do one thing for trauma healing: get better quality sleep.
Sleep quality has the greatest impact on nervous system regulation while awake than almost any other intervention.
How sleep affects trauma healing:
- Directly regulates nervous system capacity
- Reduces reaching for sugar and quick energy
- Improves blood sugar stability affecting stress threshold
- Increases window of tolerance before overwhelm
Better sleep means less fatigue, which means less reaching for fast-energy foods that destabilize blood sugar. Blood sugar instability lowers the point where you cross from stress into trauma response.
Aligning with Your Body’s Circadian Rhythm
Beyond sleep quality, align with your body’s natural circadian rhythm.
Morning light protocol:
- Get outside as early as possible after waking
- Don’t look at phone or screens first thing
- Expose eyes to natural light for 10-15 minutes
- This provides free red light therapy for your mitochondria
Red light therapy improves mitochondrial function. Better mitochondrial function means more cellular energy. More energy means greater capacity. Greater capacity means you’re less easily triggered into overwhelm.
Start Today: Practical Implementation
You don’t need complex protocols to begin. Start with awareness and sleep.
Immediate actions:
- Print a three-day nervous system tracking sheet
- Mark your state every hour for three days without judgment
- Implement a consistent sleep schedule
- Get morning sunlight within 30 minutes of waking
- Notice food choices and ask what function they serve
These simple practices reveal where you actually are versus where you think you are. That gap holds the roadmap for your healing journey.
Your body knows how to heal. You don’t need to force it, fix it, or fight it. You need to remove what blocks healing and provide conditions that support your body’s innate intelligence.
The critical line of overwhelm isn’t failure – it’s information. Brain inflammation during freeze isn’t malfunction – it’s protection. Emotional eating isn’t weakness – it’s strategy serving a function you can address directly.
Understanding transforms shame into compassion. Tracking converts confusion into clear next steps. Sleep provides the foundation everything else builds upon.
Helpful Research
Stephen Porges’ polyvagal theory provides the scientific framework for the three distinct nervous system states. His research explains how the autonomic nervous system responds to perceived safety and danger, validating the critical line of overwhelm where activation crosses into trauma. This work shows that nervous system state must be addressed before psychological processing can be effective, supporting the three-day tracking protocol.
This research establishes the biological basis for brain inflammation as part of trauma response, explaining how microglial cells become activated during stress and trauma. The work validates the freeze response mechanism where inflammation facilitates disconnection and energy conservation for survival, providing specific intervention targets beyond treating trauma as purely emotional.

Emeran Mayer’s research demonstrates bidirectional communication between gut and brain, showing how microbiome imbalances affect neurotransmitter production, mood regulation, and stress responses. This explains the trauma loop where gut dysfunction creates neurochemical problems that worsen digestive issues, validating why addressing gut health proves essential for trauma recovery.
