Are You Mad At Me? with Meg Josephson
On today's episode I welcome psychotherapist and author Meg Josephson to the podcast. Her book Are You Mad at Me? names something so many of us feel but rarely say out loud: Did I do something wrong? Are you mad at me? Meg and I talk about the fawn response, people-pleasing, and the parts of us that learned early on to stay ahead of conflict. We explore how "being nice" can disconnect us from ourselves, why grief and anger are essential to healing, and how mindfulness helps us slow down enough to notice what's really happening inside. If you've ever swallowed your needs to keep the peace, felt resentful after saying yes, or worried that one mistake could cost you connection, our conversation will resonate. We Explore: • Why "Are you mad at me?" isn't really a question, but a feeling. • The difference between being nice and being compassionate. • How grief challenges the hope that if we try harder, we'll finally be seen. • Small corrective experiences that help our parts learn we're actually safe. Here's a link to the workshop she mentioned in the episode. About Meg Josephson Meg Josephson, LCSW, is a licensed psychotherapist and the author of the New York Times bestselling book Are You Mad at Me?, which has been translated into over 20 languages.

The Courage to Start with the Ending - with Keith Miller and Courtney Corona

The Courage to Start with the Ending - with Keith Miller and Courtney Corona
On today's episode I chat with Keith and Courtney, cohosts of the podcast Tripping Over Love. Keith is licensed therapist and a Level 3 IFS Consultant, and Courtney is journalist and podcaster. They joined me to share their beautiful, messy love story. We dive into the courage it takes to start over, the "trauma" of the dating apps, and how they've used Internal Family Systems (IFS) and psychedelics to navigate the "breakups, breakdowns, and breakthroughs" of their relationship . We discuss: Starting relationships with truth instead of performance. Radical transparency — "starting with the ending" — as a foundation for trust. Why telling the truth early can save a relationship later. Loving someone while still grieving a past life. Speaking for parts instead of from them in moments of conflict. Finding the courage to try again after loss and heartbreak. Dating is messy: Getting honest about the "thrift store shopping" energy of dating apps. The difference between loving someone and being "in love." IFS as "four-wheel drive": Turning toward the model when relationships get stuck. How psychedelic-assisted journeys helped unlock grief — and create space to love again. Extended Interview At the end of our chat, I asked them each for one piece of advice for couples. This extended interviews is available for paid subscribers over on The One Inside Substack.
