Anxiety
Anxiety is a natural human emotion characterized by feelings of worry, nervousness, or unease, typically about an event with an uncertain outcome. While a normal response to stress, excessive or persistent anxiety can become a disorder, manifesting as generalized anxiety disorder, panic disorder, social anxiety disorder, or specific phobias. Symptoms may include restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbances, significantly impacting daily functioning and quality of life.
