talkwithuncertainty: understanding OCD

"What if I lose control?"

"What if I've done something terrible without realising?"

"What if this thought means something about me?"

For many people living with OCD, these questions can feel relentless.

They don't want to think these thoughts. In fact, they often find them deeply upsetting, but the harder they try to push them away, the louder they seem to become. OCD is one of the most misunderstood mental health conditions. It's often reduced to jokes about being organised, liking things neat or washing your hands a lot. The reality is very different.

OCD isn't about enjoying order or being particular. It's about becoming trapped in a cycle of intrusive thoughts, anxiety and behaviours that are intended to bring relief, but ultimately keep the cycle going.

What are intrusive thoughts?

We all have strange, random thoughts from time to time. Most people dismiss them without giving them much attention. For someone with OCD, those same thoughts can feel frightening, shocking or deeply significant. You might find yourself thinking:

"What if I accidentally harmed someone?"

"What if I shouted something inappropriate?"

"What if I'm a bad person?"

"What if I left the door unlocked?"

"What if I've caught a serious illness?"

"What if I don't really love my partner?"

The content of intrusive thoughts varies enormously, but one thing tends to stay the same. They go against what matters most to the person experiencing them, that's why they're so distressing. Having an intrusive thought doesn't mean you want it to happen or that it reflects your character. It's the meaning your brain attaches to the thought that creates the distress.

The cycle of OCD

When an intrusive thought appears, anxiety rises. To reduce that anxiety, people often do something that helps them feel temporarily reassured.

This might include:

• Checking locks, appliances or messages repeatedly.

• Washing or cleaning.

• Asking other people for reassurance.

• Mentally reviewing events to make sure nothing bad happened.

• Repeating phrases or counting in your head.

• Avoiding situations that trigger anxiety.

• Searching online for certainty.

• Comparing your thoughts to other people's experiences.

For a short while, anxiety settles, then another doubt appears.

"Yes... but what if?"

The cycle begins again. The problem isn't that these behaviours are irrational. The problem is that they teach the brain that the intrusive thought really was dangerous, making it more likely to return.

"But what if this time it's real?"

One of the hardest parts of OCD is uncertainty. Most of us can tolerate not knowing things some of the time. OCD demands certainty. It tells you that unless you're 100% sure, you can't relax. The difficulty is that absolute certainty doesn't exist. No amount of checking, researching or reassurance can satisfy OCD for long. It simply moves the goalposts.

The hidden impact of OCD

Many people with OCD keep their struggles completely hidden.

They're frightened that if they tell someone about their thoughts, they'll be judged or misunderstood. Some spend hours each day caught in mental rituals that nobody else can see. Others avoid relationships, work opportunities or becoming parents because OCD convinces them they're too much of a risk. Living with OCD can feel incredibly lonely. Not because you're alone, but because you're carrying something that feels impossible to explain.

You're not your thoughts

One of the most painful misconceptions people carry is that intrusive thoughts reveal something about who they are. They don't. In fact, the distress these thoughts cause is often a sign of how strongly they conflict with your values.

Thoughts are not intentions. Thoughts are not predictions. Thoughts are not evidence.

They're simply mental events that our brains produce every day. The problem begins when anxiety persuades us that some thoughts deserve special attention.

How therapy can help

OCD can make life feel small. You might find yourself avoiding people, places or situations that once mattered to you. Therapy offers an opportunity to understand what is keeping the cycle going and learn different ways of responding to intrusive thoughts.

As a CBT therapist, I work with people to understand how thoughts, emotions and behaviours interact. Rather than trying to get rid of intrusive thoughts altogether—which isn't possible—we focus on changing the way you respond to them.

Where past experiences are contributing to anxiety or beliefs about yourself, EMDR may also form part of our work together. Most importantly, therapy is a space where you don't have to hide the thoughts you're frightened to say out loud.

I've yet to meet someone whose intrusive thoughts shocked me. You're far more than the thoughts that happen to pass through your mind.

A final thought

If you've been living with constant doubt, endless checking or frightening intrusive thoughts, it can be easy to believe you'll always feel this way. But OCD is treatable. You don't have to spend your life chasing certainty or battling every thought that enters your mind. With the right support, it's possible to step out of OCD's cycle and start living a life that's guided by your values rather than your fears.

If you're reading this and recognising yourself, I hope you know this: you're not alone, and things don't have to stay this way. With the right support, it is possible to loosen OCD's grip and get back to living a life that's bigger than fear.
