(OCD).
People with obsessive compulsive disorder usually experience frequent obsessive thoughts and compulsive behaviours.
An obsession is an unwanted and unpleasant thought, image or urge that repeatedly enters someone's mind, causing feelings of anxiety, disgust or unease.
A compulsion is a repetitive behaviour or mental act that you feel you need to do to temporarily relieve the unpleasant feelings brought on by the obsessive thought.
For example, someone with an obsessive fear of being burgled may feel they need to check all the windows and doors are locked several times before they can leave their house.
