Anxiety is a feeling we get when we expect to feel fear.
Anxiety is also called worry, uneasiness or apprehension.
Anxiety is an emotion derived from expecting to feel fear. We feel it before an exam, in the dark, and in solitude. We also feel anxiety when entering an unknown world such as a first trip overseas. It is thought that anticipating fear makes people feel anxiety.
Anxiety makes people act more carefully, and increases their wariness. For example people thoroughly carry out safety checks when anxious. Also people become tense to be able to respond at any time.
Unlike depression, anxiety makes people unable to calm down and continue searching for a way to solve the problem.
Anxiety is an emotion in which fear is sustained/prolonged by intellect. The feeling of tension as adapted for fear also occurs in anxiety. Cautiousness when it is dark or when one is alone is natural, but it is not needed as much in today's safe society, so the tension and excitement of anxiety is excessive.
Anxiety is the fear of something which is not here. Anxiety cannot be formed without memory. It is thought that anxiety occurs because human beings have acquired good memories and imaginations, and have a notion of time.
