Anxiety disorders are a group of mental disorders characterised by feelings of anxiety and fear. Anxiety is a continuous worry about future events and a fear is a reaction to current events. These feelings may cause physical symptoms, such as fast heart rate and shakiness. Everyone feels anxious now and then. It’s a normal emotion. For example, you may feel nervous when faced with a problem at work, before writing a test, or before making an important decision, it could be anything possible. Anxiety disorders are different, though. They are a group of mental illnesses, and the distress they cause can keep you from carrying on with your life normally. For people who have one, worry and fear are constant and overwhelming, and can be disabling.
