Anxiety is a feeling of fear, dread, and uneasiness. It might cause you to sweat, feel restless and tense, and have a rapid heartbeat. It can be a normal reaction to stress. For example, you might feel anxious when faced with a difficult problem at work, before taking a test, or before making an important decision. If Anxiety does not go away and worsens over time, if symptoms interfere with daily activities, job performance, school work, and relationships, you should seek professional help.
