Obsessive - Compulsive disorder 

Obsessive-Compulsive Disorder (OCD) is a mental health condition where you experience unwanted thoughts, urges, or images (obsessions) that make you feel very anxious. To reduce this anxiety, you often feel driven to perform certain actions (compulsions) like washing, checking, or counting. These compulsions are usually repetitive and time-consuming, and they can interfere with your daily life and relationships.
