Anxiety is a natural response to stress, marked by feelings of unease, worry, or fear about uncertain situations. While it can motivate action, persistent or excessive anxiety may interfere with daily life, relationships, and well-being. It often manifests as physical symptoms like a racing heart, sweating, or restlessness, and can range from mild to severe. Common triggers include work, relationships, or health concerns, though anxiety disorders may arise without specific reasons. Managing anxiety involves techniques like mindfulness, therapy, and, in some cases, medication. Seeking support can help regain balance and improve mental health.
