When Anxiety Creates Rules: Understanding the Overlap Between OCD and Eating Disorders

Have you ever felt like your mind just won't let something go?

Maybe it's a thought that keeps popping up no matter how hard you try to push it away. Maybe it's a rule you've created for yourself that feels impossible to break. Or maybe it's the anxiety that shows up when things don't go exactly as planned.

If so, you're not alone.

One thing I often talk about with clients is how OCD and eating disorders can have a lot in common. They may look different on the outside, but underneath, they're often driven by some of the same struggles.

It's Not Really About Food

When people think about eating disorders, they usually think about food.

And while food is certainly part of the picture, it's rarely the whole story.

For many people, the eating disorder becomes a way to cope with anxiety, uncomfortable emotions, uncertainty, or a feeling of being out of control. The rules around food can create a sense of structure when life feels messy.

OCD works in a similar way.

Someone may have intrusive thoughts that create anxiety, and certain behaviors or rituals become a way to find temporary relief.

The keyword here is temporary.

The relief feels real in the moment, but before long, the anxiety comes back—and often stronger than before.

The "What If" Trap

One thing OCD and eating disorders both have in common is the endless stream of "what if" thoughts.

What if I eat the wrong thing?

What if I lose control?

What if I gain weight?

What if I don't follow my routine?

What if something bad happens?

These thoughts can become so loud that they start calling the shots. Before you know it, you're spending more time managing anxiety than actually living your life.

When Rules Start Taking Over

We all have preferences and routines. That's normal.

The problem is when those routines start feeling less like choices and more like requirements.

I've heard people describe it as feeling trapped by their own rules.

Maybe it's needing to eat in a certain way.

Maybe it's feeling like you have to exercise no matter what.

Maybe it's checking, counting, or repeating behaviors because not doing them feels unbearable.

At first, the rules might feel helpful. Over time, though, they often create more stress, more anxiety, and less freedom.

The Perfectionism Piece

Let's talk about perfectionism for a minute.

Many people who struggle with OCD or eating disorders put an incredible amount of pressure on themselves.

There's often this belief that if they can just get everything right, they'll finally feel okay.

But perfectionism has a sneaky way of moving the goalposts.

You meet one expectation, and suddenly there's another.

And another.

And another.

No matter how hard you work, it never feels like enough.

That's exhausting for anyone.

Recovery Isn't About Being Perfect

One of the biggest misconceptions about recovery is that it means never having anxious thoughts again.

If only it were that simple.

Recovery isn't about getting rid of every uncomfortable thought. It's about learning that you don't have to obey every thought that shows up.

You can feel anxious and still make choices that support your well-being.

You can experience uncertainty without letting it run your life.

You can challenge the rules that no longer serve you.

And little by little, you can build a life that's bigger than your anxiety.

A Final Thought

If you see yourself in any of this, I want you to know something:

You don't have to wait until things get "bad enough" to ask for help.

Whether you're struggling with OCD, an eating disorder, or simply noticing that anxiety seems to be taking up more space in your life than you'd like, support is available.

Healing doesn't happen overnight. But it does happen.

And you don't have to figure it all out on your own.
