Obsessive-Compulsive Disorder (OCD) is a potentially disabling anxiety disorder. People afflicted with OCD become trapped in a pattern of repetitive, senseless thoughts and behaviors that are very difficult to overcome.
Anxiety is a normal reaction to stressful situations. But in some cases, it becomes excessive and can cause sufferers to dread everyday situations.
This type of steady, all-over anxiety is called Generalized Anxiety Disorder.
