Notable Quotes

"The family cannot forget what the substance user can't remember." — Karen Moser

"Those survival parts are adaptations. They work quite well. Then people get role fatigue." — Karen Moser

"You are on a spiral staircase. There is no top. You'll continue to go deeper." — Dr. Aimie

"If we find our creativity and spontaneity, we can be out of the patterns that chain us to pain." — Karen Moser

"Can we put aside what we have to do and ask what our spirit wants?" — Karen Moser

Key Concepts

1. Relational Trauma Repair (RTR): A body-based group therapy model informed by psychodrama that helps people visit their whole-body emotions in a titrated way. Participants explore together, reducing shame and building co-regulation.

2. Floor Checks: An RTR exercise where feeling words are placed on the floor and participants move toward the one that describes their current experience. Questions build from surface to core, allowing the group to explore emotional patterns together.

3. Role Fatigue: The exhaustion that comes from carrying childhood survival roles, like the caretaker or the strong one, into adulthood. These roles serve a purpose early in life but drain capacity when maintained across every relationship.

4. Survival Strategy: An adaptation the nervous system develops to get through overwhelming circumstances. These patterns are intelligent responses that become problematic when they persist beyond the original situation.

5. Co-regulation: The nervous system's capacity to regulate in connection with another person. Group work builds this capacity by allowing people to explore difficult emotions while held by others who share similar experiences.

Episode Takeaway

I brought Karen Moser onto the show because her work with families of substance users reveals something most of us don't talk about: the nervous system cost of loving someone through their struggle. We focus so much on the person who is using that we forget the biology of the person trying to hold everything together.

What Karen describes is familiar to so many of us, whether or not addiction is part of the story. The pattern of over-helping, the inability to stop trying to control someone else's process, the slow erosion of your own health and identity. These are nervous system patterns. They started somewhere. Usually in childhood. And the body has been running that program ever since.

The work is in going back to where the adaptation started. Reclaiming the parts of yourself that got lost in the role you learned to play. And building the capacity to feel what you've been avoiding, including joy. In my book, The Biology of Trauma, Chapter 9 covers why the body holds onto these patterns and Chapter 12 walks through the three phases of the process.

Start small. The next time you notice yourself taking on someone else's emotional weight, pause. Ask your body what it needs. Not what the other person needs. What you need. That's the beginning.

Why Fixing Someone You Love Destroys Your Nervous System: The Biology of Family Trauma in Addiction

She checks his phone when he’s in the shower. She counts the meetings he attends. She holds her breath every time the phone rings at night.

She calls it love. Her body calls it survival.

If you recognize this pattern, you’re not alone. And what’s happening inside your body is more significant than most people realize. The vigilance, the monitoring, the constant bracing for the next crisis—these are nervous system responses. They are survival strategies your biology developed to navigate an unpredictable relationship.

In a recent episode of the Biology of Trauma® podcast, I sat down with relational trauma repair therapist Karen Moser. Karen has spent years working inside addiction treatment centers and with the families left holding everything the substance user numbed away. What she’s discovered about their nervous systems may change how you think about what helping really costs.

What Happens to Your Nervous System When Someone You Love Uses Substances?

When someone you love numbs their nervous system with substances, your nervous system fills in the gap. You stay present and activated for every crisis, every broken promise, every late-night worry. Your body absorbs what the other person’s body avoids. Over time, this creates a state of chronic nervous system activation that affects sleep, digestion, immune function, and emotional capacity.

Most of the attention in addiction treatment goes to the person using substances. That makes sense. They’re in danger. But what Karen’s work reveals is that the family members—the partners, the parents, the children—often carry deeper nervous system dysregulation than the person who is using.

The reason is biological. The substance user has a buffer. Chemicals suppress their nervous system’s activation. The family member has no buffer. They remain present for everything. Their biology runs a continuous activation loop without interruption.

Why Are Family Members Often More Dysregulated Than the Substance User?

The substance user numbs. The family stays present. Their nervous systems remain activated the entire time they are in relationship with someone who is using. When the substance is removed, the user’s nervous system activates for what may be the first time in years. Meanwhile, the family member’s system has been running in survival mode for the entire duration without rest.

This creates what Karen describes as a mismatch. Both people become dysregulated at the same time, but for different reasons and from different timelines. The user’s nervous system is waking up. The family member’s nervous system is depleted.

Research from Orford and colleagues, published in Drugs: Education, Prevention and Policy (2010), confirms this pattern. Family members of people with substance use issues report high rates of anxiety, sleep disruption, and stress-related illness. Their bodies carry the biological evidence of what their loved one’s chemicals suppressed.

As Karen put it during our conversation: the family cannot forget what the substance user can’t remember.

Why Sobriety Alone Does Not Repair the Family’s Nervous System

When the substance is removed, something unexpected happens. The user’s nervous system can revert to earlier developmental states. Emotions that were chemically suppressed for years suddenly surface. The person in early sobriety may become emotionally reactive in ways the family has never seen before.

At the same time, the family member’s nervous system has been running on fumes. Their capacity is gone. They’ve been holding the emotional and logistical weight of the family for years. And now the person they’ve been supporting needs even more regulation at the very moment the family member has none left to give.

This is why sobriety alone does not heal a family system. The biology of both people has been shaped by the same story, but from very different sides. Both nervous systems need attention. Both need repair.

How Childhood Survival Roles Create Adult Caretaker Burnout

Childhood survival roles—the caretaker, the strong one, the peacekeeper—are biological adaptations. They allow a child to navigate an unsafe or unpredictable environment. The nervous system learns early which behaviors keep the system stable and repeats them. These adaptations follow us into adulthood.

They make us reliable employees and attentive partners. But they also deplete our capacity over time. In the Biology of Trauma® framework, we call this role fatigue: the body’s signal that the cost of maintaining an old pattern has exceeded what the nervous system can sustain.

Karen’s work with families reveals this pattern clearly. The adult daughter who became the peacekeeper at age seven is still managing everyone’s emotions at forty-five. The son who became the strong one when his father was drinking is still unable to ask for help. These roles were not choices. They were survival strategies that the nervous system built to get through childhood.

The original ACE study by Felitti and colleagues, published in the American Journal of Preventive Medicine (1998), established that adverse childhood experiences are strongly associated with adult health outcomes. The childhood roles developed in response to those experiences are part of the biological pathway between early adversity and adult illness.

What Is Relational Trauma Repair and How Does It Work?

Relational Trauma Repair (RTR) is a body-based group therapy model informed by psychodrama. It helps people visit their whole-body emotions in a titrated way. Participants explore together, which reduces shame and builds co-regulation. The model works with the nervous system directly rather than relying on cognitive understanding alone.

One of the core exercises in RTR is called a floor check. Feeling words are placed on the floor. Participants move toward the word that best describes their current emotional experience. The facilitator then asks progressively deeper questions, moving from present-moment awareness to core patterns from family of origin.

What makes this powerful is the group element. When you name your feeling and look around, you see others standing near you. The isolation breaks. The shame reduces. The nervous system begins to register that emotional experience can happen in connection rather than in hiding.

This aligns with what Stephen Porges describes in his polyvagal theory. The autonomic nervous system detects safety and threat below conscious awareness through neuroception. When we process emotions in a group that feels safe, the nervous system receives a corrective experience. It learns that vulnerability does not automatically lead to pain.

Why Joy Can Feel as Threatening as Grief After Trauma

Joy requires openness. For someone whose nervous system learned that openness leads to loss, positive emotions trigger a protective response. The belief that something good will be taken away is rooted in early relational experience. The nervous system treats hope as a threat because historically, hope preceded pain.

This was one of the most striking observations from my conversation with Karen. In her group work, the emotions people struggle to tolerate often include joy, spontaneity, and playfulness. These are the states that were not safe in childhood. The nervous system learned to suppress them.

In Chapter 12 of my book, The Biology of Trauma, I walk through the three phases of the process that allows the nervous system to hold more of what it previously avoided. The work of titrating joy—letting in small amounts of positive experience while building the capacity to hold it—is a key part of nervous system regulation. It takes time. And it takes safety first.

How to Begin Reclaiming the Parts of Yourself That Got Lost

Karen uses an exercise in her work called the Breakthrough Timeline. Participants identify moments in their history where they showed strength, creativity, or resilience. They reconnect with the parts of themselves that existed before the role took over.

This is not about blaming yourself for the helping patterns. These patterns were adaptive. They served you. The work is in recognizing when the pattern has outlived its purpose and the nervous system is signaling that something needs to change.

The path forward includes going back to where the adaptation started. Cognitive understanding alone does not create lasting change. The nervous system needs the experience. It needs to feel what was not safe to feel before, in a container that can hold it.

Karen said something during our conversation that stayed with me: bring the part of yourself that is alive and strong into whatever you’re facing.

That is the invitation. Not to push through. Not to perform strength. But to remember that the alive, strong parts of you still exist underneath the role you learned to play. And to begin—slowly, safely—to let them back in.

Can These Nervous System Patterns Exist Without Addiction in the Family?

Yes. The pattern of over-helping, taking on another person’s emotional load, and neglecting your own nervous system regulation exists across many relationship dynamics. Addiction amplifies these patterns. But they originate in childhood adaptations that have nothing to do with substances.

Anyone who learned to be the caretaker or the strong one in their family of origin can experience the same nervous system cost. The monitoring. The vigilance. The inability to rest when someone else might need you. These are biological patterns, not personality traits.

If you recognize yourself in this description, know this: your nervous system adapted to keep you safe. It did its job well. And it can learn a different pattern. That process starts with safety, moves to support, and eventually expands into new capacity. That’s the sequence. And the sequence matters.

FAQ

1. What is Relational Trauma Repair?

Relational Trauma Repair (RTR) is a body-based group therapy model informed by psychodrama. It uses exercises like floor checks to help people identify, name, and connect around their emotions. The model is designed to be titrated, meaning participants can engage at the level their nervous system can tolerate. RTR builds co-regulation and reduces shame by allowing people to do their emotional work together rather than in isolation.

2. Why are family members of substance users often more dysregulated?

The substance user numbs their nervous system activation with chemicals. The family member stays present and activated for every crisis, every broken promise, every late-night worry. Their nervous system has been running in a survival state without any buffer. When the substance user gets sober, their nervous system begins to activate for the first time. Meanwhile, the family member’s system has been depleted for years.

3. What are floor checks and how do they work in therapy?

Floor checks are an exercise in the RTR model where feeling words are placed on the floor. Participants move toward the word that best describes their current emotional experience. The facilitator asks progressively deeper questions, moving from present-moment awareness to core patterns from family of origin. Group members share around each feeling, building connection and reducing isolation.

4. Can codependency patterns exist without addiction in the family?

Yes. The pattern of over-helping, taking on another person’s emotional load, and neglecting your own nervous system regulation exists across many relationship dynamics. Addiction amplifies these patterns, but they originate in childhood adaptations. Anyone who learned to be the caretaker or the strong one in their family can experience the same nervous system cost.

5. Why does joy feel threatening to people with trauma histories?

Joy requires openness. For someone whose nervous system learned that openness leads to pain or loss, positive emotions can trigger a protective response. The belief that something good will be taken away is rooted in early relational experiences. Building the capacity to hold joy takes gradual, titrated exposure in a safe container.
