If you have Obsessive-Compulsive Disorder (OCD), you probably find yourself plagued by persistent, recurrent and unwanted thoughts. Frequently these will involve fear of contamination or possess destructive, violent or sexual content. These "obsessions" have generally no basis in reality, yet may cause you great anxiety. In order to counteract these unwanted thoughts, you may feel yourself obliged to perform some ritual or "compulsion." Often this process will be quite time-consuming, but will give you only temporary relief from anxiety.

OCD, also called “the doubting disease,” creates fear of uncertainty and may cause you to seek frequent reassurance from others.
