For roughly twenty years, I wasn’t particularly happy. Not depressed in a clinical sense — I had a good life, a career I cared about, people I loved. But there was a persistent low-level flatness that never quite lifted. Dysthymia, it’s called. I tried psychotherapy. I meditated seriously. I read, reflected, and accumulated genuine insight into where the feelings might have originated.

None of it changed how I felt.

Here’s an analogy that captures what I eventually realized. Imagine you have a bee-sting allergy — a serious one, where a sting sends your body into full allergic reaction. Asking ‘why did the bee sting me?’ or ‘what did I do to deserve this?’ is understandable. But it’s not immunotherapy, which is what your body actually needs.

In a surprising number of psychological problems, something similar is true. Understanding the cause isn’t the treatment.

Back to my dysthymia.  After two decades with those symptoms, I noticed something important: a strong cup of coffee would briefly lift my mood. Not permanently, but enough to be a clue. A psychiatrist connected the dots and suggested Wellbutrin, an antidepressant with an activating, energizing profile. I started the medication — and within essentially one day, the dysthymia was gone. Not gradually reduced. Gone.

Being an N-of-1 experimenter by nature, I’ve stopped and restarted the drug many times over the decades since. The pattern is consistent: off the medication, symptoms return within a week. Back on, they resolve. Other family members have had nearly identical experiences. There’s almost certainly a genetic, neurochemical basis at work.

Now, I want to be clear: that’s one person’s anecdote. It is not a clinical study. But it planted a question that I’ve been sitting with ever since: why did two decades of understanding fail to move the needle, while a small molecule fixed the problem in a day? What does that say about the nature of suffering — and about what actually may resolve it, at least in some circumstances?

The Explanation Trap

That question turns out to be more than personal. It touches something universal about how human beings relate to their own pain.

We are explanation-hungry creatures. We don’t like randomness or uncertainty, so when we suffer, we go looking for a story. Why am I like this? Why do I keep reacting this way? Why can’t I stop? Finding an explanation feels like progress — and sometimes it genuinely is. But one of the quiet traps of being human is that discovering a story can create the illusion of progress.

Explanation is not the same as feeling better.

What Everyday Life Already Teaches Us

Consider something every one of us has experienced: a bad night of sleep. After one or two nights of poor rest, we’re irritable, reactive, and less able to handle stress. Problems feel bigger. The world feels harder. Then, after a good night’s sleep, life looks different again — not because we’ve gained new insight into our past, but because our physiology shifted.

The research confirms what we already intuitively know. A 2024 systematic review and meta-analysis drawing on more than 50 years of sleep-loss research found that insufficient sleep consistently worsens emotional functioning — making people feel worse and handle emotions less well. We even have folk sayings for it: “Sleep on it.” “Things will look better in the morning.” The wisdom and the science agree.

Breathwork tells the same story. Before a difficult conversation or a high-stakes moment, a few slow deliberate breaths don’t give you better self-knowledge. They settle your nervous system.

A 2023 randomized controlled trial with 100 participants found that just five minutes of daily structured breathing exercises improved mood, reduced anxiety, and lowered physiological markers of stress. The body changes first. The mind follows.

When the Stakes Get Higher: Depression and the Brain

If sleep and breath already demonstrate this principle in ordinary life, what happens when we look at clinical depression — where the suffering is deeper and the stakes are higher?

Electroconvulsive therapy (ECT) offers perhaps the clearest example. Under general anesthesia, an electrical stimulus produces a controlled seizure in the brain. It’s reserved for severe or treatment-resistant depression, and nobody suggests it works because patients arrive at a better narrative about themselves. It changes brain chemistry directly.

A meta-analysis published in The Lancet examining six randomized trials and roughly 250 patients found substantial improvement in depression symptoms, often within days to a few weeks. The parallels to my Wellbutrin experience aren’t lost on me: in both cases, something changed the state of the organism — and the emotional relief followed.

Implantable Vagus nerve stimulation (VNS) makes the same point from a different angle. A surgeon places a small pulse generator under the skin of the chest, connected to the left Vagus nerve. The device sends regular electrical pulses into the nerve that links the brain to the body’s internal organs. A 2025 systematic review across roughly 900 patients found that between one-third and one-half responded meaningfully, with many remaining in remission. Mood is not just a story we tell ourselves. It’s a biological state that can sometimes be altered by changing the body’s signaling pathways.

Rewiring Fear: Where I Am Right Now

Which brings me to the second personal thread in this episode — one that’s still unfolding.

I’m a happy person overall. I have this podcast, my wife Gail, our family, Ironman triathlon, and Madrone Springs Ranch with its kangaroos and exotic animals and bed-and-breakfast guests. But when I exercise hard, fears reliably surface: fear that I can’t handle the discomfort, that I’ll run out of energy, that I’ll quit and feel ashamed. As an Ironman triathlete, those fears rob real joy from something that’s central to my life.

I’ve spent years trying to understand those fears — meditating on them, observing them, naming them. No change. The fears persist exactly as before.

So I’m now trying something different: EMDR, or Eye Movement Desensitization and Reprocessing. In a structured session, I call up the fearful memory or sensation while tracking a ball moving back and forth on a screen. The bilateral eye movement appears to help the brain reprocess and loosen the grip associated with those fear memories. It’s been studied primarily in PTSD — where specific traumatic memories trigger fear responses — and the mechanism isn’t fully understood. Does the bilateral focus put the brain in a better state for rewiring? We genuinely don’t know.

What we do know is that it works for many. A meta-analysis of 12 randomized trials in approximately 700 people found EMDR substantially more effective than no treatment in reducing trauma-related fear. EMDR isn’t about understanding where a fear came from. It’s about directly retraining the brain’s response to it.

Desensitization therapy works on the same principle — think of it as allergy shots for fear. Repeated, graduated exposure in a safe setting doesn’t give you insight into why you fear heights or snakes; it retrains the alarm response through direct experience.

A meta-analysis of 16 studies found substantial reductions in anxiety for people treated with desensitization therapy for fear of heights. Like ECT, gains may diminish over time without reinforcement — but the initial effect is real.

I don’t have PTSD, and I’m not presenting my early EMDR experience as evidence of anything. But I’m struck by the possibility that I may still feel the physical reality of hard exertion — the discomfort, the labored breathing — while losing the fears that have become tangled up with those sensations. Physiology might change something that understanding never touched. Again.

An Emerging Frontier Worth Watching

It would be incomplete to close without mentioning psilocybin — early, promising, and still highly experimental. Part of the excitement is the concept of neuroplasticity: the brain’s ability to change its connections. Recent reviews suggest psilocybin may temporarily increase neuroplasticity, potentially making entrenched negative patterns more amenable to change. It’s not a therapy to seek out today. But it points toward a future where the biology of belief and fear becomes directly targetable — which, if my own experience is any guide, may be exactly where the real leverage lives.

A Clarification Worth Making

None of this is an argument against insight therapy. Therapy can be genuinely valuable for grief, relationship challenges, difficult life decisions, and making sense of long-standing patterns. Insight can be true, deep, and meaningful.

The point is narrower: insight can be real and still not relieve suffering. When that’s the case, it’s worth asking whether the problem is biological — and whether a biological or physiological intervention might help where understanding has not.

The Bottom Line

The mind loves stories. The nervous system sometimes needs retraining. Those are two different things — and confusing them is one of the quieter traps of being human.

If you’ve been working hard to understand your anxiety, your depression, your fears, and the understanding hasn’t brought relief, that’s not a failure of effort or intelligence. It may simply mean the solution lies somewhere else: in a good night’s sleep, a breathing practice, a medication, a nerve stimulator, or a structured therapy that works not by explaining fear but by directly retraining the brain’s response to it.

I spent twenty years understanding my dysthymia. A small molecule fixed it in a day. I’ve spent years understanding my exercise fears. A screen with a moving ball may yet do what meditation could not.

Relief often comes when physiology changes. That’s not a dismissal of the mind. It’s a reminder that the mind rides on a body — and sometimes, that’s where the work needs to happen.
