It's time to celebrate Multiple Personality Day on March 5! This day was created in 2005 to recognize and celebrate the complex, often misunderstood condition known as Dissociative Identity Disorder (DID). DID is a mental disorder in which a person has two or more distinct personalities. It can be an extremely challenging disorder for those affected, but it is also something that should be celebrated and embraced. Multiple Personality Day aims to do just that - to create awareness, spread understanding and acceptance of those living with DID.
