Have you ever felt anxious or nervous while attempting a test, visiting a new place, or on the first day of college or job? While change is inevitable, so is this uneasy feeling.

But if it gets prolonged, extreme and starts interfering with your daily activities, then it could be a sign of anxiety disorder.
