Obsessive-Compulsive Disorder (OCD) is characterized by uncontrollable anxious thoughts or behaviors. Individuals with OCD are plagued by persistent, unwelcome thoughts and images or by the urgent need to engage in certain rituals. Some OCD sufferers may only have obsessive thoughts without the related rituals. The disturbing thoughts or images (e.g., fear of germs) are called obsessions, and the rituals performed to try to get rid of them (e.g., hand washing) are called compulsions. For example, people who are obsessed with germs may wash their hands excessively. The individual is not happy to be performing the ritual behaviors but finds this to be the only way to get temporary relief from the obsessive thought.
Social anxiety disorder (previously called social phobia): People with social anxiety disorder have a general intense fear of, or anxiety toward, social or performance situations. They worry that actions or behaviors associated with their anxiety will be negatively evaluated by others, leading them to feel embarrassed. This worry often causes people with social anxiety to avoid social situations. Social anxiety disorder can manifest in a range of situations, such as within the workplace or the school environment.
