Anxiety is not a disease but a symptom.
Most people have anxiety at some time or the other in their life.
Usually, it is a normal reaction to a stressful situation and is therefore short-lived. Anxiety can adversely affect your work if it occurs often. It is important to remember that anxiety can exist alone or in combination with other symptoms of several emotional disorders. It is the most common feature of majority of psychiatric illnesses. Anxiety affects everyone, especially when there is excessive mental or emotional stress.
