Parts work is a way of noticing that you’re not a single, steady voice in your head. Instead, your mind often feels like a small community of different voices — some loud and bossy, some small and frightened — each trying to keep you safe or meet needs. One of the most well-established frameworks for this is Internal Family Systems (IFS), which treats these inner voices as “parts” that can be known, listened to, and invited into healthier roles.
Think of it like this: one part of you might be a perfectionist who nags you to work harder; another might be a kid who wants comfort and play. When those parts fight, your life feels like a tug-of-war. Parts work gives you tools to slow the fight down and get curious instead of reactive.
Todd is not a metaphor. He’s an alter — a discrete protective part of me that has its own instincts and rules. When Todd shows up, his first job is to keep me safe. He’s hyper-vigilant, suspicious of strangers, and quick to tell me to run if he senses danger. That vigilance has kept me out of harm’s way at times, but it’s also caused real conflict between me and Will: Todd interprets certain social cues as threats and sometimes acts before I’ve had a chance to evaluate them. For people living with dissociative states or strongly distinct alters, this kind of internal protection is common and usually rooted in past trauma.
Protective parts like Todd often form because something in the past made the system feel unsafe. Their job—protect at all costs—can become extreme. That’s how you get a part that screams “run” even when the actual risk is small. In relationships, that kind of quickness to flee looks like distrust, coldness, or lack of commitment. It’s maddening for partners who see the surface behavior and not the scared part driving it.
A core idea in parts work is that no part is inherently malicious; each part developed its strategy for a reason. A protector’s strategy can outlive the danger that created it. The aim becomes: understand the protector’s fear, thank it for trying to help, and then invite it to take on a less extreme role so the rest of you can live more freely.
There’s a pattern: Will laughs at a joke with someone at a party; Todd stiffens. “That’s a setup,” Todd whispers. “You’ll get embarrassed. Leave.” My mouth goes dry. My body goes half-out the door. Will, puzzled, asks if I’m okay. I don’t always have language in that moment. Later, when I can breathe, I’ll ask Todd to speak. “I smelled them before you did,” he’ll say. “I remember the way a hand used to hurt.” He doesn’t want to hurt Will; he wants to keep me alive in ways that made sense when danger was constant.
Naming that sequence aloud—“Todd, I hear you want to protect me”—is the first small step out of reflex. When I slow down enough to ask Todd why he’s reacting, he almost always points to fear. That’s the humanizing pivot parts work invites.
Because I’m not a clinician, I’ll only share low-risk, curiosity-based moves that helped me open space between Todd’s shout and my action:
If the internal material feels intense or you have trauma history, please reach out to a trained clinician. Parts work can reveal big, old wounds that benefit from skilled support. NAMI and other trusted organizations offer guidance if you’re navigating dissociative experiences or need help finding a provider.
