Anxiety is a normal reaction to stress, but when persistent and uncontrollable, it becomes an anxiety disorder characterized by excessive fear, worry, and physical symptoms like rapid heart rate, dizziness, and tension.
Caused by genetic, environmental, and neurological factors, it affects the brain's danger-detection system, causing it to overreact. Common types include generalized anxiety disorder, panic disorder, and social anxiety disorder. It significantly affects daily life, often causing social withdrawal, disruption of work/school, and sleep problems.
