Anxiety is a feeling of uneasiness, apprehension, or tension you feel in response to stressful or threatening circumstances.
Some people feel more anxiety than others.
Anxiety can either be mild or so intense that you feel panic. Normally anxiety is temporary, but when it lasts a long time or occurs in the absence of a stress or threat, it is considered an illness. When anxiety is so extreme that a person is in a panic state, then the anxiety is a psychiatric disorder known as a panic disorder. The signs and symptoms of anxiety can be classified into two categories, psychological and physical. Anxiety is diagnosed by interview.
