Hiding the knives: how avoidance keeps harm OCD alive

Gisela Ramirez4 min read16 June 2025

Never alone with the baby. Knives in a locked drawer. Each precaution feels responsible and each confirms to your brain that the danger was real. Here is the way back.

The precautions feel responsible. You have put the knives in a drawer you do not open. You make sure someone else is always in the house when the children are home. You do not drive when you are tired, because of the thoughts about the pedestrians. You have stopped bathing the baby alone. From the outside these look like the actions of a careful person, and in a sense they are. From the inside they are a cage that gets smaller every month.

I want to talk about avoidance in harm OCD, because it is the compulsion people are least likely to recognise as one, and because getting it back is where the treatment does most of its work.

What avoidance teaches your brain

Every time you avoid the situation, two things happen. You get relief: the anxiety drops, because the feared moment has been prevented. And your brain files the event: that was dangerous, and avoiding it was necessary. The relief is the reward, and the filing is the cost.

Over time the file gets thick. Hundreds of avoided moments, each one recorded as a danger successfully managed. The brain, reading the file, concludes that the danger must be real, because look how much managing it has needed. The thoughts get louder, the alarm gets more sensitive, and the list of things to avoid grows to match.

This is how avoidance maintains the fear. You have never once found out what happens when you are alone with your child, because you have never let it happen, and so the prediction that something terrible would occur has never been tested.

The safety behaviours that hide inside ordinary life

Avoidance is rarely total. More often it is woven into routine in ways that are hard to see. Standing on the far side of the platform. Keeping your hands in your pockets around people. Holding the baby in a particular way. Not looking at the knife block. Choosing the route with no bridges. Making sure the conversation never goes quiet enough for the thought to arrive.

Each of these is a small avoidance, and each carries the same lesson. Part of the early work in CBT with exposure and response prevention is simply making the list, and the list is nearly always longer than people expected.

Why willpower has not worked

You may have tried to stop. Decided, one morning, to take the knives out of the drawer and cook normally. It went fine for a while, then the thought arrived at full volume, the anxiety peaked, and the knives went back. That is what happens when exposure is unplanned, unsupported and abandoned at the peak, rather than any failure of resolve. Escaping at the peak is itself an avoidance, and it files the same lesson: that was too dangerous to stay in.

Exposure works when it is gradual, repeated, chosen by you, and stayed with long enough for the anxiety to come down on its own. That is a different thing from gritting your teeth, and it is what we build together.

Getting the situations back

We build a ladder. It starts with something you could do this week, and it ends with the thing you want back: cooking with the family, bathing the baby, driving without the route planned around the thoughts. Each step is agreed in advance. Nothing is sprung on you. And at each step, the task is to let the thought be there, without the compulsion, and find out what happens.

What happens, every time, is that the anxiety rises, the thought is loud, and then, given nothing to feed on, both fade. The feared thing does not occur. Your brain files a different lesson. And the next step is smaller than it looked.

What this is not

This is not about becoming careless. People without OCD do not think about hurting their children and then decide not to. They simply do not organise their lives around the possibility, because the possibility was never real. That is where we are going: the ordinary absence of the question.

Promising you that you would never do it would be reassurance, which is another compulsion, and the drawer would still be locked in the morning. What I can tell you is that the horror you feel is the opposite of intent, and that I have worked with this theme many times.

If the drawer is locked and the list is growing, there is more on how I treat harm OCD, and the ladder is built at your pace.
