The People Who Leave You Smaller

There is a conversation most of us have had with ourselves — sometimes for years. I know this person isn't good for me. I feel it every time I leave. I'm smaller after them than before. But I can't just walk away. We have history. Maybe it's me. In this episode of Resonance, Michael Trainer names something most of us have felt but never had the language for: the moment your body arrives at a conclusion your mind refuses to accept. Drawing on Dr. Stephen Porges' Polyvagal Theory, Ohio State University research showing that hostile relationships heal wounds 60% more slowly, and the batteries and black holes framework from his book Resonance, Michael makes the case that your nervous system is not your anxiety. It is your most ancient and sophisticated intelligence — and it has been trying to tell you something. This episode is not a permission slip to walk away from everyone who challenges you. It is an invitation to stop cross-examining the only witness in your life that has never once lied to you. What you'll take away: The difference between growth-discomfort and damage-discomfort. The biological cost of chronic relational dysregulation. The batteries and black holes framework for auditing your relationships. And why letting go — done with honesty and love — is sometimes the most generous thing you can do. "You are not curating a social circle. You are curating a nervous system. Choose accordingly." Michael Trainer has spent 30 years learning from Nobel laureates, neuroscientists, and wisdom keepers worldwide. He's the author of RESONANCE: The Art and Science of Human Connection (March 31, 2026), co-creator of Global Citizen and the Global Citizen Festival, and host of the RESONANCE podcast.Featured in Forbes, Inc, Good Morning America.  Follow on YouTube
