Change isn't just about what you do. It's about who you believe you are.
You start a new habit, break an old pattern, set a boundary. At first, it feels empowering. But soon, something unexpected happens: you feel uncomfortable. Lost. Maybe even sad. That's not a sign you're going the wrong way. That's the discomfort of an identity shift.
What is an identity shift?
An identity shift is the psychological process of updating your self-concept: the story you hold about who you are, what you're capable of, and how you move through the world. Unlike a behaviour change, which happens at the surface level, an identity shift happens at the level of belief. It's not just changing what you do; it's changing who you understand yourself to be.
Identity shifts are the deeper mechanism behind lasting personal growth, and they're almost always uncomfortable, because comfort is tied to the familiar, and the familiar is precisely what you're moving away from.
This is why people can do all the right things externally (start the habit, set the boundary, begin the new chapter) and still feel unsettled, even when those changes are clearly positive. The discomfort isn't coming from the actions. It's coming from the gap between the old self-story and the new one that hasn't fully formed yet. Understanding this gap, and what it actually consists of, is what makes it possible to move through it rather than retreat from it.
Signs you're going through an identity shift
Identity shifts rarely announce themselves. More often, they show up as a vague sense that something's off. Common signs include:
feeling unsettled or sad after a change you genuinely wanted
old routines, roles or friendships suddenly feeling like they don't fit
uncertainty about what you want, or feeling guilty for wanting something new
a pull back toward familiar patterns, even ones you know weren't serving you
feeling misunderstood by people who knew the "old" you
swinging between excitement about the future and grief for the past
If several of these sound familiar, you're probably not regressing. You're likely in the middle of becoming someone new.
Why change feels so uncomfortable: four reasons
The discomfort of an identity shift is specific and predictable. It tends to come from four overlapping sources, each with a distinct psychological mechanism.
1. You're grieving your old self
Even when the version of yourself you're moving away from was struggling (anxious, stuck, overstretched), it was familiar. It was known. And that familiar self was providing real psychological functions the new self hasn't yet taken over: a coherent internal narrative, a set of expectations you knew how to meet, a way of showing up that the people around you recognised.
Letting go of that, even voluntarily, even gladly, involves a kind of loss. Family therapist Pauline Boss's concept of ambiguous loss (loss without clear closure or social recognition) offers a useful lens here. Nothing external has died. You're still here. Life looks roughly the same from the outside. But something real has been released, and that release deserves acknowledgement rather than dismissal.
The discomfort of growth often contains genuine grief. Letting yourself feel that without judging it as weakness or ingratitude is part of what allows the shift to settle rather than stall.
2. You're in the in-between, and it feels like freefall
Anthropologist Victor Turner described the liminal state (the threshold between what was and what will be) as a period of genuine disorientation. You've outgrown the old identity, but you haven't fully inhabited the new one. That in-between space can feel like freefall: you've let go of the ledge you were standing on, and the new ground hasn't arrived yet.
This in-between is one of the more psychologically demanding states a person can be in, precisely because it lacks the clarity that either the old self or the new self would provide. Who am I, if not who I was? What am I allowed to want now? What do people who know me expect, and do those expectations still fit? These questions don't have immediate answers, and the discomfort of not having answers is real and valid. (If "what am I allowed to want?" is the one that catches you, the psychology of desire explores it in depth.)
The liminal space is also, paradoxically, where the most important identity formation happens. The new self is being built here, even when it doesn't feel like it. That quiet, awkward in-between deserves as much care as whatever came before it.
3. Your nervous system reads change as threat, even good change
The third reason identity shifts feel so uncomfortable is physiological, not psychological. Neuroscientists such as Lisa Feldman Barrett describe the brain as a prediction engine. Your nervous system has spent years building a predictive model of the world, including a model of you: how you behave, what you do in certain situations, what responses to expect from the people around you.
When you start behaving differently, that model gets disrupted, and disruption registers as threat. Your nervous system doesn't initially distinguish between "this is threatening because it's dangerous" and "this is threatening because it's unfamiliar." Both produce the same alert response: tension, unease, the pull back toward familiar patterns.
This is why inner safety is foundational to identity work. When your nervous system feels secure enough, it can tolerate the disruption of an unfamiliar self-concept without treating it as an emergency.
The good news is that nervous system responses to novelty decrease with repetition. The more consistently you act from the new identity, even imperfectly, even with discomfort, the more your nervous system updates its model and begins to treat the new behaviour as the expected baseline rather than the deviation.
4. The people around you expect the old you
Identity isn't held only inside your head. It's also held in your relationships. Psychologist William Swann's self-verification theory shows that people seek out feedback that confirms their existing self-view, and that the people around us tend to reinforce who we've been, often without meaning to.
So when you change, you may meet resistance from colleagues, friends or family who are used to the old version of you: the one who always said yes, always held it together, or never asked for much. That resistance isn't necessarily malicious. It's the social system adjusting. But it can make the shift feel lonelier and more uncertain than it needs to, and it's worth recognising so you don't mistake other people's discomfort for evidence that you're on the wrong path.
The three stages of an identity shift
Organisational consultant William Bridges, whose book Transitions has shaped how psychologists and coaches think about change, drew an important distinction. Change is what happens externally; transition is the internal psychological process of adjusting to it. He described transition in three stages:
Endings: letting go of the old identity, role or story, including grieving what's being lost.
The neutral zone: the in-between, where the old no longer fits and the new hasn't formed yet. This is Turner's liminal space, and usually the hardest stage.
New beginnings: the new identity starts to feel real, natural and your own.
Bridges' key insight was that new beginnings can't be rushed. You can't skip the ending or the neutral zone, however uncomfortable they are. Most of the distress people feel during change comes from trying to.
How to support yourself through an identity shift
Name what you're letting go of
The old beliefs, habits and identities being released deserve acknowledgement, not shame or dismissal. What were they doing for you? What were they protecting you from?
Saying goodbye with compassion rather than criticism allows the grief to move rather than calcify. Some people find it helps to make this concrete: writing a letter to the old version of themselves, or listing what they're grateful that self got them through. Release the labels that no longer fit, but do it consciously.
Ground yourself in values, not just outcomes
When the in-between feels destabilising, outcomes are an unreliable anchor. They're in the future and uncertain. Values are present and yours. Who are you becoming, and why does that matter to you? Returning to those questions regularly gives you a sense of direction while the new identity hasn't yet solidified into felt certainty. Getting clear on your core life priorities is particularly useful during identity transitions for exactly this reason.
Create safety as you grow
Journalling, breathwork, movement, supportive conversations, coaching: these aren't just coping strategies. They directly support nervous system regulation, which makes it physiologically possible to tolerate the discomfort of change without retreating from it. (Here are the regulation tools I recommend most often.)
When your system feels safe enough, growth becomes possible. When it doesn't, the pull back toward familiar patterns becomes overwhelming. Creating safety is not a detour from growth. It's the condition under which growth can occur.
Act as the person you're becoming, in small ways
You don't need to feel like the new version of yourself before acting like them. In fact, it usually works the other way around. Psychologist Daphna Oyserman's research on identity-based motivation shows that when an action feels congruent with who we are, we interpret difficulty as a sign the task matters, rather than a sign it's impossible.
So ask: What would the person I'm becoming do here, in a small way? Then do that one thing. Small, repeated actions are how a new identity moves from idea to evidence.
Build your change fitness
The capacity to adapt to change is a lot like physical fitness: it grows with practice. Every time you tolerate discomfort without retreating, you build evidence that you can survive the unfamiliar, and the next change becomes a little less threatening. You can build this deliberately in low-stakes ways: a new route to work, a new skill, a conversation you'd normally avoid. Each one strengthens the same capacity you'll need for the bigger shifts.
Expect growing pains, and normalise them
If you feel wobbly, uncertain or unexpectedly emotional during a period of personal growth, that's not evidence you should stop. It's evidence you're actually shifting: something real is changing at the identity level, not just the surface level. And if you slip back into old patterns along the way, that's part of the process too. The skill is gently bringing yourself back on track without shame, not never slipping at all.
Is it the discomfort of growth, or the wrong direction?
This is the question that keeps many people stuck, and it's a fair one. Not every uncomfortable feeling means you're growing. Sometimes discomfort really is a signal to change course.
The discomfort of a genuine identity shift tends to coexist with a quiet sense of rightness, even while the surface experience is uncomfortable. It often feels like stretching: effortful, unfamiliar, but expansive. The discomfort of going in the wrong direction tends to feel different. It's more like contraction or self-betrayal: a persistent sense that you're abandoning something important to you.
Some questions that can help you tell the difference:
Does this change move me toward my values, or away from them?
If the discomfort disappeared tomorrow, would I still want this?
Am I uncomfortable because this is new, or because it isn't me?
Trust the coexistence of discomfort and rightness. It's a reliable signal.
Becoming takes time, and discomfort is part of it
You don't have to have it all figured out. You're allowed to be in process. The discomfort isn't a sign you should stop; it's proof you're stepping into something new.
The new identity doesn't arrive fully formed. It's built slowly, through the accumulation of choices, through the small acts of showing up as the person you're becoming before that person feels entirely real. That's not pretending. That's how identity formation works. You act from the new self, and gradually the new self becomes the baseline.
This is also the deeper mechanism behind rebuilding self-trust. Self-trust is itself an identity, and it's built the same way: through repeated, imperfect, courageous acts of showing up as someone who follows through.
That's brave work. And you're already doing it.
If you're in the middle of an identity shift and finding the in-between harder to navigate than you expected, coaching can help you find your footing, make sense of what's happening, and move through it with more clarity and less self-criticism. I work with clients in Palmerston North and online across New Zealand, and the first session is free.

Identity shift questions people ask
Why does change feel uncomfortable even when it's good?
Because your brain and nervous system are built around the familiar. Even positive change disrupts your self-concept and your brain's predictions about you, which registers as threat until the new pattern becomes familiar.
Is it normal to grieve your old self?
Yes. Letting go of an old identity is a real loss, even when you chose the change. Acknowledging that grief, rather than dismissing it, helps the shift settle.
How long does an identity shift take?
It varies, but it's usually months rather than weeks. Research by Phillippa Lally at University College London found that new habits took a median of 66 days to become automatic, ranging from 18 to 254 days, and identity tends to follow repeated behaviour.
Why do I feel worse after making positive changes?
You may be in the "neutral zone" between your old and new identity. Feeling disoriented, emotional or unsure during this stage is common and usually temporary.
What is an identity shift in psychology?
An identity shift is a change in your self-concept: the beliefs you hold about who you are and what you're capable of. It's the deeper process that makes behaviour change last.
