Anxiety is a feeling of unease that arises as a result of potential risk or danger. The brain sends out a signal informing the body about the possible threat whilst releasing hormones and putting the body into flight or fight mode. In moderation, anxiety may be helpful to stay focused, alert, or take action when one feels under pressure (i.e. during exams, interviews or when public speaking).
However, Anxiety disorders frequently manifest in excessive and persistent worry and fear. This can cause the individual to become overwhelmed by a non-threatening situation and make it seem as if one is experiencing real danger. Anxiety can also provoke panic attacks where an individual experiences feelings of severe distress, fear, or even death. There is a likelihood that due to an underlying problem (i.e. trauma), one may suffer from an anxiety disorder. Until it is addressed, the anxiety is likely to be re-experienced.
