Anxiety

Anxiety is an emotion characterized by an unpleasant state of inner turmoil, often accompanied by nervous behavior, 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.[3] Anxiety is a feeling of uneasiness and worry, usually generalized and unfocused as an overreaction to a situation that is only subjectively seen as menacing. https://en.wikipedia.org/wiki/Anxiety
