The lexical meaning of anxiety is the sensation of fear or panic. Possible to be experienced by all in daily life, this sensation is frequent and constant in generalized anxiety disorder (GAD).
Anxiety (worries, concerns, distress) is normally a necessary part of human nature, in that it acts as a signal indicating that internal demands are waiting to be satisfied. There are many internal demands like hunger, thirst, sex etc. The body expects these to be satisfied there and then. In reality however the external world generally does not allow this to happen. In such a situation we experience anxiety. We have a series of defence mechanisms that come into play, starting from denying the presence of the stimulus all the way to ridiculing it. If the defence mechanisms prove insufficient then psychiatric disorders can set in. One of these is generalized anxiety disorder.
Anxiety… Uneasiness, tension in muscles, difficulty in focusing, early exhaustion, and almost spending the greater part of the day in worry and apprehension…
There are cases where anxiety is quite severe. These situations are named anxiety crisis or attacks by the public.
Anxiety is one of the most important functions of our mental world. It is a clear expression that our brain is in need of something.
