Many people wonder, Do I have OCD? Occasional worries, habits, or a preference for order are common, but obsessive-compulsive disorder involves more than everyday stress or routines. OCD typically includes persistent, unwanted thoughts, images, or urges that cause distress, along with repetitive behaviors or mental acts performed to reduce anxiety or prevent something bad from happening. These symptoms can be time-consuming, difficult to control, and disruptive to daily life, relationships, work, or school. While only a qualified mental health professional can diagnose OCD, learning to recognize the signs is an important first step. Understanding how OCD differs from normal concerns can help you decide whether it may be time to seek support, evaluation, or treatment.
