Turning 40 and Rewiring the Mind

In this episode, Stephanie sits down with Marcy Langlois to explore her story of survival, transformation, and healing. After a childhood marked by medical challenges, family instability, and a battle with addiction, she found sobriety—only to face a new and terrifying crisis in her mid-40s when her body began to shut down. Diagnosed with mast cell activation syndrome and histamine intolerance, Marcy was bedridden for 40 days, grappling with allergic reactions to everything in her environment—including her own thoughts. But through deep inner work, rewiring her brain, and healing her nervous system, she emerged healthier and stronger than ever.

Episode Highlights:

• A childhood shaped by medical challenges – Born with a cleft lip and palate, Marcy endured 20 surgeries between birth and age 18, and a difficult upbringing in a home affected by addiction and instability.
• The impact of unprocessed trauma – How childhood survival mechanisms carried into adulthood, leading to addiction and self-destructive patterns.
• The breaking point – At 45, Marcy’s body rebelled, leaving her unable to function and suffering from life-threatening reactions to food, stress, and even her own thoughts.
• Rewiring the brain for healing – Marcy shares how she used neuroplasticity and what she calls the "cancel method" to retrain her mind and shift her body's response to stress.
• The power of nervous system regulation – Understanding the difference between fight-flight-freeze and rest-digest-heal, and how true healing can’t happen until the body feels safe.
• Energy and frequency in healing – Why raising the body's energetic vibration was a crucial final step in Marcy’s recovery.
• Life after transformation – How Marcy is now thriving, free of chronic illness, and living with vitality and purpose.

Marcy’s story is a testament to the incredible resilience of the human body and spirit. Her journey from a lifetime of trauma and illness to vibrant health is inspiring proof that healing is possible, even when all seems lost.
