Anxiety is a general term for several disorders that cause nervousness, fear, apprehension, and worrying.

These disorders affect how we feel and behave and can cause physical symptoms. Mild anxiety is vague and unsettling, while severe anxiety can seriously affect day-to-day living. Anxiety can be defined as “an emotion characterized by feelings of tension, worried thoughts and physical changes like increased blood pressure.”

When faced with potentially harmful or worrying triggers, feelings of anxiety are not only normal but necessary for survival.
