The rules you built around never being sick

There are rules, and you probably do not call them that. You do not eat before a journey. You sit where you can leave. You scan the menu for anything that could be risky and order the same safe thing. You check the use-by date, then check it again. You know exactly who at work has been off with a bug and you keep your distance for a week. You avoid alcohol, reheated food, hospitals, children who look pale, the school run in winter.

Most people have lived with these rules for years without telling anyone what they are really about, because it sounds strange said aloud. It is not strange; it is one of the most consistent pictures I see, and I want to explain what the rules are doing.

Where the rules come from

Each rule was adopted after a moment of fear, as a way of making sure that moment did not lead to the thing you dread. Not eating before travel means less to bring up. Sitting near the exit means you can get out. Avoiding the ill colleague means you cannot catch it. Every rule has a logic, and every rule brought relief when it was first applied, which is exactly why it stayed.

And then the next rule, and the next. Emetophobia's rules multiply because the fear is about the possibility of being sick rather than any one situation, and the possibility exists everywhere, so the rules have to cover everywhere. The list grows, and the world shrinks to fit it.

What the rules cost

The cost is easy to underestimate because each rule seems small. But look at the whole list. Meals out, gone or reduced to one safe order. Travel, gone or endured hungry. Social events, managed around exits and who else is there. For some people it shapes very large decisions: not having children, or being terrified through a pregnancy, turning down a job with travel, avoiding hospitals even when they are needed. Those are big costs to carry silently, and they are usually the reason someone finally looks for treatment.

Why the rules keep the fear alive

Every rule is a safety behaviour, and safety behaviours prevent you from finding out what would have happened without them. You did not eat before the journey, and you were not sick. The rule gets the credit. You never discover that you would not have been sick anyway, because you have never travelled having eaten. The prediction underneath the rule, that without it the feared thing would happen, has never once been tested.

So the rules preserve the fear, perfectly, by ensuring it is never contradicted.

Mapping them

The first thing we do in the CBT work is write the list. All of it: the food rules, the travel rules, the people rules, the checking, the monitoring, the anti-sickness rituals, the things you carry and the places you will not go. Most people are surprised by how long it is, and by how much of their life it turns out to govern. That surprise is useful, because it makes visible the size of what the fear has taken, and it gives us the ladder.

Dropping them, one at a time

Then we climb. The ladder you build with me starts somewhere very ordinary, a word, then a written sentence, then a photograph, and works up through the foods you avoid, the places you avoid, and the rules, one at a time. Eat before the journey. Sit in the middle of the row. Order something new. Each step is agreed in advance and stays in place until it has genuinely lost its charge, and each one is an experiment: what actually happens without the rule?

What actually happens, almost always, is nothing. And that nothing, gathered as evidence in your own life, is what the rules have been preventing you from collecting for years.

The aim is not to make you vomit. That is not what exposure means and it is not part of the treatment. The aim is to make the possibility ordinary enough that you can eat, travel, drink and be around people without consulting the fear first.

If you have a list you have never shown anyone, there is more on how I treat emetophobia, and the list is where we start.
