Normal feelings of anxiety cease to be a natural, everyday occurrence when a person experiences persistent or continuous feelings of anxiety. When the anxiety is persistent for at least six months and is sufficient to prevent someone from leading a normal life, it is termed 'General Anxiety Disorder'.

Many doctors and healthcare professionals believe that the condition is triggered by an imbalance in the chemicals of the brain, leading to anxiety and sadness. While some people may be pre-disposed to this chemical imbalance, external stresses, such as relationship or work problems, bereavement, serious illness, financial problems, and alcohol or drug misuse, can also act as triggers.

Treatment of anxiety disorders includes self-help techniques, such as relaxation and breathing control, counselling, cognitive behavioural therapy, and prescription medicines, such as anti-depressants.
