People who have experienced panic attacks often go around with a grave sense of unease that at any moment they will experience a major panic attack. It is a fear of the ultimate panic attack that would finally push them over the edge. This leads people to make changes to their behavior in order not to do anything that might trigger a panic episode. When people feel this way simple daily tasks can become big challenges. Some people start to fear driving their car in traffic. Others fear leaving their safe zone or simply any situation where they have responsibilities to perform. This state of apprehension keeps a persons anxiety level high leading to feelings of general anxiety.
