Occasional anxiety is a normal part of life. You might feel anxious when faced with a problem at school, before going to a new place, taking a test, or deciding on a new path. But anxiety disorders involve more than temporary worry or fear. For a person with an anxiety disorder, the anxiety does not go away without intervention. The feelings can interfere with your daily life such as anxious to go to school because worry of being bullied, need to check the stove 5x before leaving the house, worry to embarrass oneself at a public area. There are several different types of anxiety disorders. Examples include generalized anxiety disorder, panic disorder, and social anxiety disorder.
Most likely, children who are experiencing anxiety, will have muscular tension, pacing, feeling worries and fatigue.
