When you are anxious, you can feel afraid and worried, and it can affect your body (e.g., stomachaches, can’t sleep), thoughts (e.g., what-if thoughts), and behaviour (e.g., avoiding things). A person has an anxiety disorder when anxiety is excessive and gets in the way of daily life and activities (e.g., a person who is unable to meet new friends or go to social get-togethers; a person who worries about being perfect to such an extent that they are unable to complete their work by the due date, etc.).
