You’re in the supermarket and your knees nearly buckle. You’re driving and suddenly you can’t see through the tears. You’re in a meeting and something in your chest opens like a trapdoor and you have to excuse yourself to sit in a toilet cubicle and shake.

This is grief. Not the tidy, linear grief of self-help books. The real thing. The kind that ambushes you at petrol stations and ruins Tuesday afternoons. And if nobody has told you this yet, let me tell you now: this is not a sign that you’re doing it wrong. This is what it looks like when the body is doing it right.

The Nervous System’s Dosing Mechanism

Your nervous system is spectacularly intelligent. One of its most important jobs is to prevent you from being overwhelmed by experiences that are too big to process all at once. And deep loss the kind that rearranges the architecture of your life is always too big to process all at once.

So the system parcels it out. It gives you a wave of feeling, lets you crash into it, and then pulls you back to shore. It opens the door to the grief, lets you stand in it for as long as you can bear, and then gently closes it so you can function. Make dinner. Answer emails. Get the children to school.

Think of it like this: if you tried to download an entire ocean through a garden hose, the hose would burst. Your nervous system is the hose. The grief is the ocean. The waves are the system’s way of downloading what it can handle, resting, and coming back for more. Each wave is a portion of processing. Each return to baseline is recovery. The oscillation is the healing.

Why the Waves Are Unpredictable

One of the most disorienting things about grief is its apparent randomness. You’re fine at the funeral but destroyed by a cereal box. You hold it together at Christmas but fall apart on a nondescript Wednesday in March. The waves seem to follow no logic, no calendar, no respectful schedule.

This makes sense when you understand how the nervous system processes loss. It’s not processing the event. It’s processing the absence and the absence shows up in a thousand small, unpredictable moments. Every time you encounter something that was woven into your life with the person who’s gone, your system registers the gap. A particular brand of coffee. The empty side of the bed. The silence where their laughter used to be.

These are not just emotional triggers. They are nervous system disruptions. Your body built an entire regulatory ecosystem around this person’s presence their smell, their warmth, their rhythm. When they’re gone, every point of contact becomes a point of recalibration. And recalibration hurts.

The Body of Grief: Why Loss Is So Physical

Grief is not an exclusively emotional experience. It is a full-body event. The heaviness in the chest that makes breathing feel effortful. The bone-deep exhaustion that no amount of sleep resolves. The digestive disruption, the immune system dips, the strange aches that materialise in places you didn’t know could ache.

This happens because the person you lost was part of your regulatory landscape. In attachment terms, they were a co-regulator someone whose presence helped your nervous system feel safe, calibrated, and grounded. Losing them is not just losing a person. It’s losing a source of nervous system stability. It’s like removing a load-bearing wall from a building. The entire structure has to redistribute its weight, and that redistribution is physically taxing.

This is also why grief is so exhausting even when you’re not actively crying or thinking about the loss. Your nervous system is working overtime behind the scenes, recalibrating thousands of micro-connections, adjusting to a world that no longer includes this person’s heartbeat in its background rhythm.

Why the Five Stages Model Misleads

Most people have heard of the five stages of grief: denial, anger, bargaining, depression, acceptance. This framework, originally developed by Elisabeth Kübler-Ross in the context of terminal illness, has become the dominant cultural model for understanding loss. And while it has helped many people feel less alone, it has also done real harm because it implies that grief is a tunnel with an exit.

In reality, grief doesn’t move in a straight line. It spirals. You might feel acceptance on Tuesday and be back in raw, gutting denial by Thursday. You might skip anger entirely and live in bargaining for months. You might reach what you think is acceptance and then hear a particular song and discover an entire unmapped continent of sorrow you didn’t know existed.

The nervous system doesn’t follow frameworks. It follows its own biological rhythm of activation and rest, approach and retreat, feeling and recovering. Trying to force grief into a linear progression is like trying to force the tide to rise in a straight line. It rises and falls. It advances and retreats. And it reaches places you didn’t expect, at times you didn’t plan for.

Riding the Waves Instead of Fighting Them

The most important shift in grieving is moving from fighting the waves to learning to ride them. This means releasing the expectation that you should be ‘over it’ by now. It means allowing the tears to come without immediately labelling them as regression. It means understanding that a bad day after a string of good days is not failure it’s the next layer of processing surfacing because your system is ready for it.

When a wave arrives, let it arrive. Don’t try to outrun it or intellectualise it or compress it into something manageable. Notice where it lives in your body. Breathe into that space. Let the tears come if they want to. Let the anger surface if it needs to. Let the numbness wash through if that’s what arrives. The wave will pass. They always do. Not because you forced it, but because that’s what waves do.

Between the waves, be gentle with your nervous system. Sleep when you can. Move your body slowly not to ‘work through’ the grief, but to keep energy circulating. Eat warm food. Be near people who feel safe, even if you don’t want to talk. Let someone sit with you in silence. Let them make you tea. Let yourself be cared for, even if every instinct tells you to handle this alone.

Grief is not a problem to solve. It is not a phase to get through. It is the price of love, and the nervous system’s way of honouring what was lost by refusing to let it be processed cheaply or quickly.
