Obsessive Compulsive Disorder (OCD) is an anxiety related condition and consists of repetitive thoughts and/or actions.
People who suffer from OCD experience repetitive unwanted and unpleasant intrusive thoughts and images and these are called obsessions. Common obsessions include fears of contamination and germs, of harming ourselves or others or of being harmed, or having upsetting violent or sexual thoughts.
People suffering with obsessive compulsive disorder (OCD) find these intrusive thoughts very upsetting and anxiety-provoking, particularly as they tend to go against their personal and moral values. Sufferers of OCD engage in compulsive behaviours to try to alleviate their distress, such as carrying out mental rituals (counting, repeating etc) or performing particular behavioural rituals (avoidance, washing hands, checking etc).
