anxiety

Anxiety is an emotion characterized by an unpleasant state of inner turmoil, often accompanied by nervous behaviour such as pacing back and forth, somatic complaints, and rumination.[1] It is the subjectively unpleasant feelings of dread over anticipated events, such as the feeling of imminent death.[2] Anxiety is not the same as fear, which is a response to a real or perceived immediate threat,[3] whereas anxiety is the expectation of future threat.
