Obsession, or fixation, refers to an intense and persistent preoccupation with a specific idea, object, or person. This mental state can lead to repetitive thoughts and behaviors that dominate an individual's mind, often interfering with daily life and responsibilities. Obsessions can manifest in various forms, such as compulsive behaviors or an overwhelming desire to achieve a particular goal. In psychology, obsessions are often associated with conditions like Obsessive-Compulsive Disorder (OCD). Individuals experiencing obsession may find it challenging to control their thoughts, leading to anxiety and distress. Treatment options typically include therapy, medication, or a combination of both to help manage symptoms and regain control.
