OCD is a complicated condition that many people may not be aware of or know much about. The condition is difficult to understand as individuals with the disorder might act unremarkably in other aspects of their lives. However, individuals with OCD may have an obsession and associated compulsive behaviors that are highly unusual, like fearing they will run people over, so they repeatedly check under their vehicle. The fear of possibly harming someone can be distressing, causing anxiety and avoidance behaviors. By learning about the disorder in detail, loved ones can better understand and support those going through it. Learning about OCD treatment can also help them encourage the affected individuals to continue therapy.
