Stuck Not Broken

A paper co-authored by 39 scientists called the Polyvagal Theory "untenable" — and now psychology influencers are announcing the Theory is "dead." But is it?
I'm Justin Sunseri, therapist and member of the Polyvagal Institute's Editorial Board. That means I review work for Polyvagal Theory accuracy. So let me actually look at the claims.
In this episode, I break down Paul Grossman's paper "Why the Polyvagal Theory Is Untenable." We need to objectively check whether his criticisms accurately represent what the theory actually says. Because if they don't, the counterarguments are moot.

Is your self-help routine actually making things worse?
The self-help industry has one answer for everything: do more. More habits, more discipline, more effort. But for a nervous system that's already overwhelmed — stuck in sympathetic flight/fight, freeze overdrive, or dorsal shutdown — more doing can mean more frustration, more overwhelm, and more defeat.
In this episode, I break down 5 common self-help habits that may be working against you if you don't yet have the nervous system capacity for them.

Stop forcing yourself to relive the most painful moments of your life before your body is ready to handle them.
Traditional therapy often skips the most critical step — building the physiological capacity to actually process what comes up. Justin Sunseri breaks down why flooding your system with past trauma makes things worse, and what to do instead.

Does a mental health diagnosis explain why you are suffering, or does it just give your suffering a name?
In this episode, I challenge the traditional way we look at mental health labels. While a diagnosis (like depression, anxiety, or ADHD) can be a helpful shorthand for professionals, it often becomes a trap for the person receiving it—convincing them they are "broken" rather than adapting to their life context.
To illustrate this, I share the story of two hypothetical clients: Penny and Milton. Both come to therapy with the exact same heavy symptoms.
Penny receives a diagnosis, is told she has a disorder to manage forever, and leaves feeling defective.
Milton is met with a nervous system perspective, learns his feelings make sense based on his history, and is given the tools to actually heal.

Join me as we explore why your diagnosis is a description, not a life sentence. We’ll discuss how to shift from "fighting a disorder" to building safety in your nervous system, so you can stop merely managing symptoms and start getting unstuck.
In this episode, you will learn:
Why a diagnosis in the DSM describes what is happening but rarely explains why.
The critical difference between the "Disorder Model" vs. the "Nervous System Model."
How to stop rejecting your feelings and start building safety (the "Milton" approach).
Why your symptoms are likely a normal response to an abnormal situation.
