As Someone With Chronic Illness I Live in a Body That Keeps Changing the Rules
The Rules Changed Again
Last Tuesday the rules changed. Not metaphorically—literally. My body, which has been operating under one set of constraints for the past several months, shifted. The symptom that was managed became unmanaged. The medication that was working stopped working as well. The baseline I had adjusted to is no longer the baseline. This is what living with chronic illness actually looks like, and it is different in a specific and important way from what most people imagine when they imagine being sick. Most people imagine a fixed state. They imagine that you have a thing, the thing has characteristics, and those characteristics are what you manage. What they don't imagine is that the characteristics keep changing.
The Illusion of Stability
When you live with a condition that fluctuates, you develop a complicated relationship with good periods. A stretch of relative stability is genuinely good news, and you try to receive it as such. But underneath the relief is always a kind of waiting. Not pessimism, exactly—more like an honest accounting. The ground has shifted before. It will shift again. What you do with the good period matters. Some people use good periods to rest. Some use them to accomplish things that aren't possible during flares. Some try not to think about it too hard and just live, which is also legitimate. There is no correct answer, and the people who have opinions about which approach is right have usually not lived inside a body that doesn't hold still.
What Medical Uncertainty Feels Like
A particular challenge of many chronic conditions is that medicine does not have clean answers. The mechanisms are not fully understood. The available treatments work for some people and not others, or work for a while and then don't, or work but with costs that require their own management. Treatment is often iterative guesswork conducted by people who are doing their best with incomplete information. Being a patient in that system requires holding two things simultaneously: trust in the people trying to help you and clear-eyed awareness that they don't have certainty to offer. That is not a comfortable position. It requires a kind of tolerance for ambiguity that nobody trains you for.
What the Research Tells Us
A study from the University of Michigan examining psychological adaptation in patients with relapsing-remitting conditions found that the most consistently difficult element was not the severity of symptoms during bad periods but the unpredictability of when those periods would occur. Uncertainty about the future, not the current difficulty, was the primary driver of psychological distress. Separately, researchers at Ghent University studying coping strategies in chronic illness found that flexible coping—the ability to shift strategies depending on current capacity rather than committing rigidly to one approach—was associated with better quality of life outcomes than consistency of strategy alone. Adaptability, in other words, was protective. Which makes sense when the thing you're adapting to keeps changing.
The Grief That Nobody Schedules
There is grief in chronic illness that is ongoing rather than resolved. Not grief for a single loss but repeated small griefs—for the plan that had to be cancelled, for the version of yourself that existed before this started, for the certainty about tomorrow that you no longer have. That grief doesn't follow a clean arc. It doesn't resolve and then stay resolved. It recurs in rhythm with the illness itself. People who haven't experienced this sometimes find it hard to understand why someone isn't better-adjusted by now, as if adjustment is a task you complete rather than a process you remain in indefinitely. The adjustment is never finished because the thing you're adjusting to keeps changing.
The Unexpected Gifts
I'm reluctant to package this with a bow, but honesty requires acknowledging what has actually been true alongside what is hard. Living in a body that keeps changing has made me genuinely more present. When stability is not guaranteed, you stop deferring presence to some later time when conditions are better. The good Tuesday is actually good, and you know it while it's happening. It has also shown me with unusual clarity who in my life can hold this with me without requiring me to perform wellness I don't have. That knowledge, however it was acquired, is not nothing.
What I Carry
I carry a calendar that is always provisional. I carry a mental model of my own body that is revised regularly. I carry the ongoing work of explaining, or deciding not to explain, what is happening to people who want a simpler story. And I carry the knowledge that I am still here, still adapting, still finding the edges of what is possible in the life I actually have, not the one I planned for.
