Anxiety is undue concern or worry. It prepares your body for action to battle danger. But what if there’s no danger? Then, anxiety obliges the sufferer to keep fleeing from an unseen beast to an alien destination. If you’ve run this race before and feel like a champion, then you know the effects of anxiety – trouble at work, school, home, and with relationships. But help is available, through clinical therapy, hospitalization, and medication like ketamine.
