Anxiety is a feeling of unease, such as worry or fear, that can vary widely in degree of severity. Some feelings of anxiety can be perfectly normal, such as before an exam, job interview or in a challenging situation. Anxiety is a positive part of a natural instinctive process to survive in the external environment. The body tries to create a balance. However, if there has been a prolonged period of difficulty, such as relationship, financial or work problems, ill health, or bereavement, for example, or traumatic childhood or even current experiences, then anxiety becomes difficult to control. It becomes more constant and has no particular, rational reason; it may be that life experiences could be triggering an ongoing instinct to face challenges, adapt and survive, long past the need to do so.
