When You Only Have Fifteen Years

On finitude, the nervous system, and what it means to live consciously through cancer

Somewhere in the middle of my first diagnosis, I stopped sleeping properly.

Not just because of the treatment, though that was part of it. It was the thinking. The moment my head touched the pillow, something in me would begin — a low, relentless accounting of everything I had not yet done, everything that might still be taken from me, everything I should be feeling but wasn't quite able to reach. The night became a battleground. And my own mind was both the general and the enemy.

I didn't know then what I know now: that a nervous system in a state of threat cannot do two things at once. It cannot protect you and let you rest. It cannot brace for impact and allow the body to regenerate. Those are mutually exclusive physiological states. And the mind — when it isn't trained, when it hasn't been given a different job — will always choose vigilance over stillness.

The nervous system doesn't know the difference between a frightening thought and a real threat. It responds to both the same way.

What I've been sitting with lately is the question of time. Not in the way a diagnosis makes you think about time — that raw, nauseating arithmetic of how much do I have left — but something quieter than that. Someone recently put it plainly: of all the years a person lives, only about fifteen are truly free. When you subtract sleep, work, errands, childhood, all the time that belongs to other people and other obligations, you're left with perhaps fifteen years that are genuinely, entirely yours.

I read that and I felt two things simultaneously. First, a familiar contraction — the one I know from hospital waiting rooms, from scan results, from all the moments the body tightens against a truth it hasn't yet fully received. And then something else: a strange, quiet spaciousness. Because a person who has been through cancer already knows this. We already know that time is not infinite. The diagnosis just made us look at it directly.

The trouble is, knowing that time is finite doesn't automatically change how you use it.

I've watched this in myself, and I see it in the people I work with. You survive something enormous. The treatment ends. The scans improve. And then life rushes back in — the emails, the obligations, the noise — and before long you're living the same way you lived before the diagnosis, only now with the added weight of feeling like you should be living differently. Like you were given a second chance and somehow you're wasting it.

That guilt is its own kind of suffering. And it is, I want to say gently, a misunderstanding.

Because the reason people don't change after a near-death experience isn't lack of desire or lack of insight. It is because the nervous system hasn't changed. The body is still in a posture of defence. The mind is still running the same calculations it ran in the waiting room: brace, protect, survive. And from inside that posture, you cannot build a conscious life. You can only react to the one you already have.

This is the most important thing I know about healing: the nervous system is not a side issue. It is the whole issue. It is where transformation either becomes possible — or doesn't.

There's a phrase I return to often: my mind is my friend, not a second obstacle on top of the world's many obstacles. I've spent a long time trying to actually make that true. Not as a slogan, but as a practice.

Because here's what I know from living through cancer three times: the mind will tell you things that feel absolutely true but are not. It will tell you that rest is weakness, that stillness is giving up, that you should be doing more, feeling more. And if you let the mind become your second adversary — you will exhaust yourself long before the illness gets the chance.

The practice I keep returning to is almost embarrassingly simple. Before the body can rest, the mind needs a different assignment. Invite the part of you whose only job tonight is to prepare for renewal — the version that gently reminds all the other anxious, productive parts: tomorrow exists. The body has its own intelligence. Lying down is not retreat. It is medicine.

There's a question I sometimes ask the people I work with, especially early on: what would you do with your time if you weren't afraid?

It usually takes a moment. Because underneath that question is the deeper one: what actually matters to you? Not what you think should matter. What, when you hold it up honestly, would still feel meaningful when you're gone?

This is not a morbid question. It is the most clarifying question I know. Cancer already asked it — in a language you couldn't ignore. The invitation now, in the recovery, in the remission, in the middle of treatment, wherever you are — is to let your actual answer shape your actual days.

Small practices. That's where it begins. Not an overhaul of your life. A breath before bed. A consistent time you put down the screen. A morning ritual that says: I am a person who takes care of themselves. One minute, twice a day, where you simply notice what your body is holding.

These are not luxuries. They are the compound interest of a conscious life. The slow, quiet way you move from someone who is surviving cancer to someone who is actually living.

Healing is not a destination. It is every breath, every choice, every restful moment — the whole way through.

I didn't begin this work because I had the answers. I began it because I had survived something three times and still didn't fully know how to live well. The framework I now share with others was first a framework I built for myself — out of necessity, out of exhaustion, out of a deep need to finally stop fighting my own body and start listening to it instead.

If you are somewhere in the middle of this — treatment, recovery, the strange aftermath where the support falls away and everyone expects you to feel grateful and you mostly feel tired — I want you to know: you are not behind. You are not failing. You are not broken.

You are someone whose nervous system has been doing the most extraordinary job of keeping you alive under impossible conditions. The work now is not to demand more of it. The work is to meet it. To give it the conditions it needs to regulate, to rest, to come back to something that resembles peace.

That is not a small thing. That is, in my experience, everything.
