anxiety

anxiety extract from Britannica Online.

In psychology, a feeling of dread, fear, or apprehension, often with no clear justification. Anxiety differs from true fear in that it is typically the product of subjective, internal emotional states rather than a response to a clear and actual danger. It is marked by physiological signs such as sweating, tension, and increased pulse, by doubt concerning the reality and nature of the perceived threat, and by self-doubt about one's capacity to cope with it. Some anxiety inevitably arises in the course of daily life and is normal; but persistent, intense, chronic, or recurring anxiety not justified by real-life stresses is usually regarded as a sign of an emotional disorder.
