OCD can be a bully.

Obsessive-compulsive disorder is a mental health condition involving unwanted, distressing intrusive thoughts, images, or urges, followed by physical or mental compulsions that provide temporary relief from overwhelming anxiety.

This cycle can create deep feelings of fear, shame, and guilt, eroding a person's self-esteem while consuming hours of their day.

The condition remains widely misunderstood. It isn't a personality trait, a quirk that keeps people organised, or simply a fear of germs. While contamination fears do affect some, OCD can latch onto anything, often targeting the things a person cares about most.

Understanding obsessive thoughts

Intrusive thoughts include unwanted images, urges, demands, doubts and questions that encourage compulsions.

Examples of compulsive behaviour

It can look like a new mum afraid to hold her baby after experiencing an intrusive image of harming them. It can mean hiding kitchen knives out of fear of losing control, repeating a specific phrase until it “feels right”, or retracing a driving route to check that no one has been accidentally hurt.

Often, the person with OCD knows these intrusive thoughts are irrational and the compulsive behaviour is excessive or unrealistically connected. However, the unbearable weight of uncertainty drives the compulsion anyway. 

Because relief from compulsions is always short-lived, the cycle inevitably resets.

Understanding covert mental compulsions

What the outside world sees is usually just the tip of the iceberg. Many compulsions happen entirely inside someone's head, a pattern informally referred to as Pure OCD, or Pure-O. Mental compulsions can include:

  • Obsessively analysing memories, intentions, or bodily reactions for proof of wrong-doing.
  • Silently repeating phrases or prayers until anxiety eases.
  • Mentally reviewing every detail of an event to reassure yourself.

Everyone experiences intrusive thoughts

What's important to know is that everyone experiences intrusive thoughts. The difference is that OCD creates doubt in your mind and convinces you that the thoughts mean something about your character. 

We want you to know that thoughts do not define you, and feeling anxious is not proof that you are defective. 

Treatment for OCD

While OCD can feel debilitating, it is treatable. Evidence-based treatment typically includes specialised Cognitive Behavioural Therapy, specifically Exposure and Response Prevention, alongside medication, such as SSRIs.
