We are all born with an internal smoke alarm. For most people, it is set to a reasonable sensitivity. Let’s call it a 50/100. If you burn the toast, it beeps. If there is an actual fire, it screams. If you wave a tea towel (that you scrambled to find) at it for a minute, it eventually settles down. This is logical and fair.
But OCD is like having a smoke alarm that goes off because the toast looks slightly darker than it did yesterday. It goes off because you had a passing thought about a candle, or because it cannot tolerate the tiny possibility that a fire might start at some point in the next decade.
That is the core of the struggle. OCD is not just about “worrying a lot.” It is a glitchy threat system that treats uncertainty as if it were an immediate physical danger. It then pressures you to do something to make that feeling go away right now.
“Just tell me it is okay”
We have all been there. You might have said it yourself, or felt the desperate itch to ask questions like:
- “Are you sure I locked the door?”
- “Do you think I am a bad person for thinking that?”
- “Are you sure I didn’t accidentally upset them?”
In the moment, these questions feel responsible. It feels like you are just “checking.” The truth is that reassurance does work, at least for a few seconds. You ask, they answer, you feel your body unclench, and the alarm finally stops shouting.
However, there is a catch. In the context of OCD, reassurance does not actually teach your brain that you are safe. Instead, it teaches your brain: “Good catch. I am glad I had that alarm to warn me.”
Instead of calming the system down over time, you are reinforcing the idea that the “smoke” was real. You are teaching the alarm to be even more sensitive the next time.
The leaky bucket
If reassurance truly solved OCD, one good answer would be enough. But OCD does not hold onto certainty very well. It is more like a bucket with a hole in the bottom.
You get the answer you need and you feel better, but then the certainty starts to drain out. Before long, “Are you sure?” turns into “How sure?” and then “But what if you missed something?”
At this point, you are no longer looking for information. You are performing an emotional ritual. You are trying to buy a feeling of safety that OCD is simply not designed to let you keep.
When loved ones get involved
Partners, parents, and friends usually start out with the best intentions. They answer the questions because they hate to see you hurting. They check the stove for you because it feels easier than watching you struggle.
In clinical terms, this is often called “family accommodation.” It is a kind-hearted gesture that accidentally keeps the OCD pattern alive. It recruits the people you love into the disorder, shrinking everyone’s life until the whole household is busy serving the smoke alarm.
It is an incredibly difficult position for everyone:
- If they reassure you, the OCD grows.
- If they do not, you feel alone and panicky.
The goal is not to be harsh or dismissive. The goal is to learn how to be supportive without feeding the alarm.
Retraining the alarm system
In therapy, specifically Cognitive Behavioural Therapy (CBT) with Exposure and Response Prevention (ERP), we change the target. We stop trying to find the perfect reassurance and start practising how to tolerate “not knowing.”
It sounds simple in theory, but it is hard work in practice. The process looks something like this: Alarm (Anxiety) > No Reassurance > Anxiety rises > Anxiety falls anyway.
When you allow that anxiety to drop without “fixing” it with a ritual, your brain eventually learns the most important lesson in recovery: “I can tolerate how this feels”.
How to respond to the beep
Recovery is not the moment the alarm never beeps again. It is the moment you can hear the beep and choose not to reorganise your whole life around it.
This means choosing “good enough” instead of “perfectly sure.” It means staying with the urgency without acting on it. You might say things like:
- “Maybe I did, maybe I didn’t. I am practising not knowing.”
- “I don’t need a 100% guarantee to move on.”
- “That is just the alarm being glitchy. I am going to leave it alone.”
These are not just affirmations. They are practice for your nervous system.
Reassurance is like pressing the snooze button on a broken alarm. You get silence for ten minutes, but the noise is guaranteed to return. True recovery comes from learning that certainty isn’t the cure.
Tolerance is.
