What Is IFS Therapy? How "Parts Work" Heals
A client once sat across from me, looked at the floor, and said: “Part of me really wants to get better. But another part of me doesn’t trust this at all.” Then she laughed, a little embarrassed, like she’d said something strange.
She hadn’t. She’d just described, perfectly, the everyday experience of being a person — and she’d described the starting point of the kind of therapy I do most often. In my Mississauga office, that sentence isn’t a problem to fix. It’s the doorway.
We are all made of parts
If you’ve ever said “part of me wants to, but part of me is scared,” you already understand the core idea of Internal Family Systems, or IFS. We talk to ourselves in the plural because we are plural — not in any worrying way, but in the ordinary way that every mind is made up of different inner voices, moods, and reactions.
There’s the part that pushes you to work harder. The part that wants to cancel the plans and stay home. The inner critic that narrates your mistakes. The part that goes quiet and numb when things get to be too much. IFS calls these parts, and its central insight is gentle but radical: none of them are bad. Even the ones that cause you the most trouble are usually trying, in their own clumsy way, to protect you.
That reframe alone tends to loosen something in people. So much of the suffering I see isn’t just anxiety or low mood — it’s the war people wage against their own reactions. Why am I like this? Why can’t I just stop? IFS sets that war down.
The part you might not know you have
Here’s the part of IFS that I find most hopeful, and it’s the reason I trained in it. Underneath all of those protective parts, IFS holds that there is a core in each of us — it calls this Self — that is calm, curious, and compassionate. Not a part, but the steady “you” that’s still there underneath the noise.
You’ve met your Self before. It’s the version of you that can sit with a friend in pain without panicking, that knows the wise thing even when you don’t do it, that feels settled on the rare quiet morning. IFS doesn’t try to install something new in you. It works to clear enough space that this steadier you can come forward and lead.
What “parts work” actually feels like in a session
People sometimes imagine therapy as either reliving the worst day of your life or being handed a worksheet. IFS is neither.
A session usually starts with whatever is loud that week — the anxiety before a meeting, the snapping at your kids, the heaviness you can’t explain. Instead of arguing with that feeling or rushing to make it go away, I’ll invite you to get curious about it. Where do you notice it in your body? If that anxious part could speak, what is it worried would happen if it stopped?
It can feel unfamiliar at first to turn toward a feeling you’ve spent years trying to outrun. But something shifts when a protective part finally gets to explain itself — when the harsh inner critic admits it’s terrified of you being humiliated, or the numb part reveals it shut everything down years ago because feeling was simply too much at the time. These parts aren’t your enemies. They’re often young, and tired, and have been working overtime without thanks.
From that calmer, curious place, the relationship changes. You stop being at the mercy of the reaction and start being in a kind of dialogue with it. Over time, the parts that have been carrying old pain — what IFS calls burdens — can begin to set those weights down. The anxious part doesn’t have to run the whole show anymore. It gets to rest.
Why this matters for trauma especially
Many of the people I work with don’t think of themselves as trauma survivors. They had “normal” childhoods, nothing dramatic, nothing they’d put in that category. And yet they carry a relentless inner critic, or a deep difficulty trusting people, or a body that braces for impact when nothing is wrong. If any of that sounds familiar, it can help to read about the signs of complex childhood trauma in adults.
IFS is particularly suited to this kind of quiet, complex trauma. It doesn’t require you to dredge up and re-tell every painful memory in detail, which for some people simply re-floods the nervous system. Instead, it works at the pace your protective parts allow, with their permission, so that healing happens with your system rather than against it. For people who’ve felt unsafe in their own minds for a long time, that pacing can be the difference between therapy that overwhelms and therapy that finally helps.
Is IFS the only thing we do? No.
I want to be honest, because therapy marketing can make every approach sound like a cure-all. IFS is my home base, but it isn’t the right tool for every moment. Sometimes what helps most is the practical structure of CBT, the skills of DBT for riding out intense emotion, or the relationship focus of EFT for couples. Several of the therapists on our team work primarily in those modalities. Good therapy isn’t loyalty to one method — it’s meeting the person in front of you with what they actually need.
What I love about IFS is that it tends to make the other work go better, because it changes your relationship with yourself first. It’s hard to use a coping skill when one part of you is busy attacking you for needing it.
