Almost everyone has unpleasant or unwanted thoughts at some point, such as thinking they may have forgotten to lock the door of the house, or even sudden unwelcome violent or offensive mental images.
But if you have a persistent, unpleasant thought that dominates your thinking to the extent it interrupts other thoughts, you may have an obsession.
Some common obsessions that affect people with OCD include:
- fear of deliberately harming yourself or others – for example, fear you may attack someone else, such as your children
- fear of harming yourself or others by mistake – for example, fear you may set the house on fire by leaving the cooker on
- fear of contamination by disease, infection or an unpleasant substance
- a need for symmetry or orderliness – for example, you may feel the need to ensure all the labels on the tins in your cupboard face the same way
You may have obsessive thoughts of a violent or sexual nature that you find repulsive or frightening. But they're just thoughts and having them does not mean you'll act on them.
Compulsions starts as a way of trying to reduce or prevent anxiety caused by the obsessive thought, although in reality this behaviour is either excessive or not realistically connected.
For example, a person who fears contamination with germs may wash their hands repeatedly, or someone with a fear of harming their family may have the urge to repeat an action multiple times to "neutralise" the thought.
Most people with OCD realise that such compulsive behaviour is irrational and makes no logical sense, but they cannot stop acting on it and feel they need to do it "just in case".
Common types of compulsive behaviour in people with OCD include:
- cleaning and hand washing
- checking – such as checking doors are locked or that the gas is off
- ordering and arranging
- asking for reassurance
- repeating words in their head
- thinking "neutralising" thoughts to counter the obsessive thoughts
- avoiding places and situations that could trigger obsessive thoughts
Not all compulsive behaviours will be obvious to other people.
It's important to get help if you think you have OCD and it's having a significant impact on your life.
If you think a friend or family member may have OCD, try talking to them about your concerns and suggest they get help.
OCD is unlikely to get better on its own, but treatment and support is available to help you manage your symptoms and have a better quality of life.
There are 2 main ways to get help:
- refer yourself directly to a psychological therapies service – find a psychological therapies service in your area
- see a GP – they'll ask about your symptoms and can refer you to a local psychological therapies service if necessary
