Anxiety is a common emotional response to stress, characterized by feelings of unease, fear, and apprehension. While it's a natural reaction to life's challenges, excessive or prolonged anxiety can become a mental health concern. Symptoms may include restlessness, rapid heart rate, and racing thoughts. Anxiety disorders, such as generalized anxiety disorder and social anxiety disorder, are more severe and require professional intervention. Effective treatments, including therapy and medication, can help individuals manage anxiety and improve their quality of life.
