Anxiety includes such experiences as worry, dread, the anticipation of something negative looming in the near future; it includes restlessness, distractibility, inattention and problems with immediate memory. Sometimes anxiety is tied to a specific person, event, or place. Mostly, anxiety is vague, ill-defined and its presence is not tied to anything specific; it is more free-floating. Anxiety is always accompanied by unwanted physical sensations such as ‘butterflies in the stomach,’ muscle tension, heaches, tightness in the chest, hot or cold sensations in the arms and feet, dizziness, and nausea. Treatment includes cognitive behavioral therapy (CBT) and can include medication when the symptoms are severe and/or there is a significant family history of anxiety problems.
