Why Do I Always Assume The Worst About My Health?

A headache is a tumour. A twinge is something spreading. Your mind does not consider the ordinary explanation and then rule it out. It leaps to the catastrophe first and treats everything milder as denial. This is not stupidity and it is not weakness. It is a strategy, and like most strategies that run your life without your consent, it was built for a reason, in conditions where expecting the worst may genuinely have protected you.

If you have real symptoms, see a doctor. This names a pattern, it is not medical advice and it is not for crisis. Notice what the worst-case habit is trying to do. If you assume the catastrophe, you can never be blindsided by it. Bracing for the terrible thing feels like control, like a way to be ready, like a shield against the horror of being caught unprepared. The mind would rather live in a rehearsed disaster than in an unpredictable calm, because the disaster, at least, it can see coming.

This is usually learned. Somewhere earlier, hope was punished. You let yourself expect good and got hurt, or you grew up where the bad thing did keep happening and vigilance was the only thing that softened the blow. So the system concluded that expecting the worst is safer than being surprised by it. It carried that conclusion into adulthood and pointed it at your body, because the body is the one place where the worst really is, eventually, true, which makes it the perfect ground for the habit to feel justified.

The catastrophic assumption is agency aimed at the wrong target. The wish underneath is to be safe, to not be destroyed by something unforeseen. That wish is good. It has simply been handed a strategy that cannot work, because you cannot pre-live your way out of every danger, and trying to costs you the life happening now.

You do not argue a catastrophising mind into optimism, and I will not tell you to think positive. You go to the place that decided the worst was always coming and ask what happened there, what taught it that hope was dangerous. That is the real work. If you want a quiet, free place to begin, the book Before Approaching the Threshold was written for it.
