In this episode of Field Notes, Dr. Rob Downey sits down with integrative psychiatric provider Dr. Josh Waddell to unpack mental health through a functional medicine lens—moving beyond symptom labels and "chemical imbalance" shortcuts to ask what's actually driving anxiety, depression, and emotional instability in the first place.

Dr. Waddell lays out a clear roadmap for understanding mental illness as a progression—from real-world triggers to cellular/mitochondrial disruption to downstream neurotransmitter changes—then introduces his practical "Four Pillars" framework (Body, Mind, Spirit, Environment) to help people pinpoint where their system is wobbling and what to address first.

The conversation is equal parts compassionate and actionable, emphasizing that mental health struggles are not a character flaw, that healing is often about restoring stability in the right pillar(s), and that the best plan is the one that meets you where you are—sometimes including medication as a bridge so deeper root-cause work can actually stick.

5 Key Takeaways

Mental health symptoms often follow a progression: triggers → mitochondrial/cellular dysfunction → neurotransmitter changes, so "root cause" usually sits upstream of brain chemicals.

The Four Pillars (Body, Mind, Spirit, Environment) offer a simple way to identify what's most off—and why progress can stall when you're only focusing on one area.

You can't out-supplement a toxic context: chronic stress, unhealthy relationships, burnout jobs, or constant distressing media exposure can keep the nervous system stuck.

A timeline exercise (mapping life events, illnesses, stressors, and turning points) can reveal the earliest catalyst and clarify where to start.

Supplements can help, but basics matter: food-first, third-party testing, avoid vague proprietary blends, and match herbs/supports to your symptom pattern—not trends.
