Anxiety is a feeling of unease, such as worry or fear, that can be mild or severe.
Everyone has feelings of anxiety at some point in their life. For example, you may feel worried and anxious about sitting an exam or having a medical test or job interview. During times like these, feeling anxious can be perfectly normal.
However, some people find it hard to control their worries. Their feelings of anxiety are more constant and can often affect their daily life.
Anxiety is the main symptom of several conditions, including panic disorder, phobias, post-traumatic stress disorder and social anxiety disorder (social phobia).
However, the information in this section is about a specific condition called generalised anxiety disorder (GAD).
