I’ve spent more than three decades in exam rooms.
I’ve ordered thousands of tests, delivered diagnoses that changed lives, and sat with patients through fear, relief, and everything in between.
But the most important thing I’ve learned about healing didn’t come from a textbook, a conference, or a clinical trial.
It came from watching what fear does to patients, to doctors, and to the relationship between them.
Early in my career, a new patient walked into my office. He was fifty, obviously overweight and out of shape, but cheerful. Before he’d finished his first sentence, something happened in my brain that I didn’t have language for at the time.
A thought arrived, fully formed: If something happens to him, it will be on me.
Not: How can I help him?
Not: What does he need?
Just fear. Dressed up as medical responsibility.
That moment stayed with me. Because I realized it wasn’t isolated — it was the norm. And it was happening on both sides of the stethoscope.
Medicine trains doctors to be certain. To project authority. To never let them see you sweat.
What that training actually produces, though, is a nervous system on constant alert.
I’ve watched doctors dismiss a patient’s question about unconventional approaches, not because there was no evidence, but because the question felt like a challenge. I’ve seen treatment decisions driven by the fear of being blamed, not by what the patient actually needed. I’ve sat in rooms where two people — one in a white coat, one in a paper gown — were both scanning for danger, and neither of them knew it.
What I call the Automatic Brain—the part of us that reacts to threat before reason has a chance—doesn’t care about credentials. A medical degree doesn’t quiet it. If anything, it often gives it a louder microphone.
In my second year of medical school, while preparing for my first board exam, I felt my heart skip a beat. Then another. I checked my pulse. It felt irregular. I had my blood pressure taken: 130/80. Not alarming by most standards, but to a twenty-three-year-old medical student already trained to detect danger, it felt ominous. The next day, sitting in an exam room, I could feel my heart pounding as the cuff tightened around my arm again and again. Each reading seemed to confirm that something was wrong. Doctors grew concerned. Tests were ordered. And with every step, fear gained authority.
What I understand now is that the fear was not coming only from the numbers. It was coming from meaning. My grandfather had died young of an apparent heart attack. So had my uncle. My Automatic Brain had already linked heart-related symptoms with danger. By the time that cuff began to hum, it was not simply measuring blood pressure. It was confirming a story my fear had already written.
And there was another layer beneath that. Somewhere much earlier in life, my young brain had also learned that mild illness brought a certain kind of care and focused attention. Without realizing it, I had formed an association between being unwell and being held close. That is how complicated fear can be. It does not only protect us from pain. Sometimes it also protects old attachments, familiar roles, and patterns that once felt safe.
That experience taught me something medicine never did: symptoms may be real, but the meaning we attach to them is often where fear does its deepest work. And when that fear goes unnamed, it can shape both sides of the stethoscope—the patient desperate for certainty, and the doctor too uncomfortable to sit with uncertainty long enough to truly see what is happening.
That experience didn’t just change how I understood myself. It changed how I saw every patient who sat across from me after.
Many, if not most, patients don’t fail to heal because of wrong diagnoses or wrong treatments.
They fail because fear is running both sides of the conversation — and nobody names it.
The patient is afraid to ask the question they most need answered. The doctor is afraid to sit with uncertainty long enough to actually listen. Both leave the room having gone through the motions of care without ever touching the thing that most needed attention.
The AB doesn’t announce itself. It shows up as a clipped tone, a rushed visit, a diagnosis that provides certainty more than clarity, a symptom that keeps someone safely connected to care they fear losing.
I’ve seen patients worsen after treatments improved their pain — because the pain had been doing something for them. Providing structure. Predictability. Permission to rest. To the AB, wellness can feel more threatening than suffering, because at least suffering is familiar.
That idea can feel uncomfortable. It was uncomfortable for me to write. But it’s what thirty years of watching people showed me.
This is why I wrote Fear Is a Liar.
Not to explain neuroscience. Not to offer another self-help framework.
But because the single most obstructive force I’ve witnessed in healing — in patients, in doctors, in myself — is the fear we don’t recognize as fear.
The voice that sounds like reason. The symptom that feels like truth. The certainty that’s actually camouflage.
Once you can see it, something changes. Not immediately, not completely. But the AB loses its authority the moment you stop mistaking it for you.
