We all experience change. Some of it is planned — the move we finally made, the decision we'd been quietly circling for months. Some of it arrives without asking permission. And sometimes it starts even quieter than that: an ordinary moment when a thought lands and simply won't leave.

Something has to change.

I recently found myself navigating a significant change. I knew what needed to shift. I knew, too, that I was the only person who could make it happen.

What I didn't know was what came next.

That gap — between knowing you need to change and knowing what the new normal will look like — is one of the most uncomfortable places to stand. If you're standing there right now, I want you to know: what you're feeling has a name, a shape, and a reason. None of it means you're doing it wrong.

The body knows before the mind catches up

Once the realisation lands — even before you've worked out what happens next — the body often responds first.

Racing thoughts. A racing heart. Restlessness. Poor sleep. That strange, disorienting cocktail of excitement and anxiety that leaves you feeling wired and exhausted in the same afternoon.

If any of that sounds familiar, you're not broken — you're in a stress response. It's one of the most common experiences people describe once they've realised a change is underway, and it tends to arrive long before the thinking catches up. Physiologically, the body doesn't fully distinguish between a threat to safety and a threat to certainty. It prepares for both in much the same way.

Why the "not knowing" feels so loud

Our brains like finished stories. When there's a gap in the narrative — an ending we can't yet see — the brain goes looking for the missing pieces, drawing on past experience to predict what happens next.

And the brain has one job above all others: to keep us safe.

So when the future is uncertain, it doesn't go looking for the best-case scenario first. It goes looking for the threat, because historically, that's what kept us alive.

What if it doesn't work? 

What if I've made the wrong decision? 

What if I fail?

This isn't a personality flaw or a confidence problem. It's a well-documented feature of how we're wired. Recognising it for what it is — biology, not prophecy — can be the first small act of taking back control.

The curve isn't a straight line

There was a period of elation, once the decision was made. I felt lighter, excited about what might come next.

Then the uncertainty returned. 

I recognised this as part of what's often called the Change Curve — a model with roots in the work on grief and loss, later adapted to describe how we move through any significant change: shock, resistance, exploration, and eventually, acceptance.

It's usually drawn as a neat, single dip — down, then up. Tidy enough for a training slide.

But change isn't linear. We move forward, then backward, then forward again. We revisit feelings we thought we'd already worked through. This time, though, I wasn't just looking at the Change Curve from the outside.

I was feeling it.

What actually shifted

Eventually, something shifted. 

Me.

My thoughts changed. My behaviours changed. The future started to feel less like something I needed to predict, and more like something I could shape.

If you're in the messy middle right now

A few questions I return to, and sometimes ask the people I work with:

• What might it cost you to stay where you are?

    If nothing changed over the next year, what potential risks or consequences might you be accepting?

• When have you navigated significant change successfully before?

    What strengths, qualities or resources did you draw on then that you could bring to this change now?

• Imagine the change has become your new normal. What is different?

    What are you doing, thinking or feeling that tells you the change has been accepted — and what has become possible as a result?

You don't need the answers today. Sometimes just sitting with the question is enough to loosen something. We tend to weigh the risk of changing carefully, and barely weigh the risk of not changing at all.

Maybe that's the real opportunity

Not that every change is positive. Not that difficult experiences need to be repackaged into a lesson. Some change is simply hard, and it's allowed to be.

But change can create space. For a new perspective. A new direction. A different version of ourselves.

We don't always get to know what's waiting on the other side of the curve.

Perhaps we don't need to.

Maybe we just need to discover that we can navigate the uncertainty along the way.

We don't grow by avoiding change. We grow by discovering we can change.
