Uncertainty and Mental Health with Sarah Bergenfeld and Martha Sweezy

We are excited to celebrate the launch of IFS Collected Wisdom: Conversations with Experienced Voices in Internal Family Systems a book that brings together voices, reflections, and lived experience from across the IFS community. This book was created from a desire to honor those voices, and to acknowledge that wisdom in IFS doesn’t live in one place or one person. It lives in relationship, in experience, and in the field as it evolves. Thank you for being a listener, for being part of this community,  and for continuing to explore what becomes possible when Self leads. We hope that IFS Collected Wisdom can become a companion in your IFS journey. Here is a link to the IFS Collected Wisdom book contents. The Role of Uncertainty in Mental Health with Sarah Bergenfeld and Martha SweezyIn this episode, we welcome two leading voices in Internal Family Systems therapy for a conversation that bridges neuroscience, sensory experience, and healing. Sarah Bergenfield is a certified Level 3 IFS practitioner, writer, and educator specializing in autistic individuals and couples. Autistic herself, Sarah weaves together IFS, polyvagal theory, predictive processing, and sensory science in her clinical and consultation work. She teaches internationally for clinicians working with neurodiverse clients, and her work reframes autism not as a deficit, but as a condition of sensory surplus. Martha Sweezy is an assistant professor of psychiatry at Harvard Medical School, program consultant and supervisor at the Center for Mindfulness and Compassion at Cambridge Health Alliance, and a psychotherapist in private practice in Northampton, Massachusetts. She teaches IFS nationally and internationally and has authored and co-edited numerous books on the model, including Internal Family Systems Therapy, Second Edition (with Richard Schwartz), Intimacy from the Inside Out (with Toni Herbine-Blank), and Internal Family Systems Therapy for Shame and Guilt.Together, Sarah and Martha are co-authors of Wired to Feel: Autism as a Condition of Sensory Surplus.In this episode, we explore the role of uncertainty in mental health: how it can quietly drive distress and shame, and how IFS offers a path toward resolution. While the conversation has special relevance for autistic systems, the insights apply across all neurologies.
