In December 2020, I was sick and tired of being sick. I had been ill for 25 years, homebound for ten. Disabled. Exhausted. Frustrated.

I had asthma, digestive dysfunction, 22 years of undiagnosed Lyme and Bartonella, lifelong unknown mold exposure, Graves’ disease, SIBO, severe neuropathy, interstitial cystitis, severe ligament laxity, and the list went on. I was down to ten foods I could tolerate for over two years, and I was gaining weight.  I struggled to stand. Walking was difficult. My brain fog was debilitating. I was constantly fatigued and in pain.

I worked with wonderful practitioners, many specializing in Lyme and mold illness, yet nothing truly moved the needle. Maybe you’ve been there: trying protocol after protocol, killing pathogens, binding toxins, searching for the missing piece. I began to lose hope.

The Cost of Being Sick

Chronic illness didn't just take my health—I spent my 30s, 40s, and much of my 50s sick and disabled. For ten of those years, I was homebound, unable to travel or attend weddings, holidays, and birthdays. I often had to cancel at the last minute because my body simply wouldn't cooperate. There is a quiet grief that comes with that kind of isolation. You watch life happen from the sidelines, and you learn to conserve energy for basic survival. 

One of the deepest losses was not being able to participate in my son’s life the way I had imagined. As a mother, you picture being present, showing up fully, volunteering, traveling, and celebrating milestones. Instead, there were seasons when I was simply trying to get through the day. There is guilt that comes with that, and heartbreak.

Financially, the burden was immense. Years of practitioner visits, chasing symptoms, specialized testing, supplements, remediation, and lost earning capacity. When illness stretches on for decades, it impacts not just your body, but your stability, your identity, and your future planning. And what makes it even harder is when people don’t understand, when labs are confusing, when symptoms don’t fit neatly into boxes, and when environmental illness is minimized or dismissed. The cost of illness is not theoretical. It is measured in missed years, missed memories, and missed opportunities. But then, unexpectedly, someone asked me a question that would change everything.

The Moment Someone Named It

I was in health coaching school, hoping that by learning more about the body, I might finally uncover what had been missed in my own health. In an unexpected twist, a fellow health coach, Bobbi McGrath, gently suggested something no one had clearly explored before: “Have you ever considered Mold Toxicity or Chronic Inflammatory Response Syndrome?” 

That question stopped me. Despite years of working with skilled practitioners, no one had fully connected my symptoms under the umbrella of chronic inflammatory response syndrome. No one had suggested I investigate exposure to a water-damaged home. 

I remembered we had a water leak in our home when our son was two and we did not address the leak properly.  I did not know about mold and its negative impact on health. Then, my parents told me my childhood bedroom had black mold hidden in the wall. That conversation led me to pursue deeper testing, and for the first time, the pieces began to fit together.

When Everything Finally Made Sense

In December 2020, everything shifted. For the first time, I approached my illness differently. Not as separate diagnoses, but as one underlying condition: Chronic Inflammatory Response Syndrome (CIRS)—a biotoxin illness triggered by exposure to mold and other microbial toxins. Biotoxins are produced by living organisms such as mold, bacteria, parasites, and even viruses. When the body cannot properly clear them, inflammation becomes chronic, systemic, and debilitating.

In hindsight, my many diagnoses weren’t separate problems; they were expressions of a dysregulated internal terrain. What changed wasn’t another aggressive killing protocol; it was a regenerative approach focused on:

• Nervous system regulation
• Opening detox and drainage pathways
• Deep cellular nourishment
• Gut restoration
• Mitochondrial support

Addressing the total toxic and pathogenic load gently, instead of forcing my body, I began supporting it. Within three days, my diet began expanding. Three months later, my brain fog lifted and my ligament laxity resolved. Six months in, my walking improved. Twenty-three months later, after nearly three decades of illness, I no longer met diagnostic criteria for Lyme, mold illness, or CIRS. I was no longer disabled, and I continued healing beyond that point. True healing is about restoring resilience.

It Wasn’t Just Lyme, It Was the Environment

Environmental exposure was a major piece of my story. Like so many people, I had unknowingly lived and worked in water-damaged environments for years. When we fail to recognize the impact of indoor air, people suffer quietly for decades, as I did.

And this is why organizations like the Change the Air Foundation are so important. We need better public awareness of water-damaged buildings. We need improved indoor air standards. We need early recognition of symptoms. We need education for practitioners. We need validation for patients. No one should lose decades of their life to an undiagnosed environmental illness.

Three Things That Actually Moved My Healing Forward

1. Nervous System Work

At the time, I didn’t even realize that’s what I was doing. I practiced breathwork, grounding, and time in nature. I worked with a biblical counselor and I studied scripture. For me, focusing on truth and faith became brain retraining. My body had lived in fight-or-flight for decades. You cannot heal in survival mode. Regulating my nervous system created safety in my body again, and that safety allowed detox and repair. 

2. Nourishing My Body

When I increased whole foods, especially fruits, vegetables, and nutrient-dense superfoods, everything shifted. Inflammation began coming down and detox pathways began functioning better. This was about replenishment. Everyone is bio-individual. Listening to your body matters. Avoiding foods you don’t tolerate is important, but many chronically ill individuals are profoundly undernourished at the cellular level. You cannot detox effectively if you are depleted.

3. Opening Drainage Pathways

This is the piece I see missed often. If bile isn’t flowing, if bowels aren’t moving daily, if lymph is stagnant, if kidneys are overwhelmed, toxins recirculate. When drainage pathways are not supported, people experience worsening symptoms like pain, rashes, fatigue, and inflammation, and they assume detox is “too much” or they’re regressing. Often, they simply need better foundational support. Proper drainage decreases die-off symptoms. It allows detox to be tolerable, even gentle. And gentle healing is sustainable healing.

From Patient to Practitioner

As I began the long road of recovery, I learned something that many patients are still discovering today: they are out of the mold, they are taking binders, they are treating infections, but their nervous system is still in survival mode. Their drainage pathways are congested. Their bodies are too depleted to detox safely. Without addressing the whole picture, progress stalls.

My 28-year journey shaped how I now practice. I don’t chase symptoms; don’t force detox; I don’t layer aggressive protocols onto fragile systems. I take a nervous-system-first approach. Layered healing: nutrition → drainage → detox → repair. Listening to the body instead of overriding it. Today, I work with individuals struggling with Lyme, mold illness, and CIRS—many who feel like they’ve tried everything. I help them:

• Identify environmental contributors
• Support the internal terrain
• Reduce toxic load gradually
• Restore resilience
• Avoid years of unnecessary trial and error… because I lived it

Healing Is Possible

Healing is not linear; it is layered. When interferences are removed and the body is supported properly, it has an extraordinary capacity to repair, even after decades. I am living proof. If you are in the middle of your own long healing season, I encourage you to reflect:

• Does your body feel safe?
• Are you nourished or depleted?
• Are your drainage pathways supported?
• Are you addressing the whole picture, not just one pathogen or one toxin?

Healing is possible. Not because we force it, but because the body was designed for it. If you're reading this and see yourself in my story, know that you're not alone—and more importantly, you're not without hope. The path forward may look different than you imagined, but it exists. Sometimes we just need someone who's walked it to show us the way.
