I have OCD (an anxiety disorder) otherwise known as Obsessive-Compulsive Disorder. In every day speech, it's common for people with a tidy bedroom or desk to proclaim themselves as "OCD." Obsessive-Compulsive Disorder, however it is a mental illness that means so much more than an affinity for organization. OCD is characterized by repetitive, unwanted thoughts (obsessions) + irrational, excessive urges to do certain actions (compulsions). OCD is distressing + anxiety-evoking.
