Anxiety describes feelings of worry, nervousness, fear, apprehension, concern, or restlessness. Feelings of anxiety often serve as an “alarm system,” alerting one to danger. In more normal but busy situations, anxiety can provide the energy to get things done; however, sometimes anxiety can be out of control, giving a sense of dread and fear for no apparent reason. This kind of anxiety can be disruptive. As many as 25% of the population experiences some form of anxiety on a daily basis.
