What is Anxiety ?
Anxiety is an unpleasant, disagreeable and vague sense of feeling and is characterised by uneasiness, restlessness and apprehension. Individuals with anxiety often experience symptoms like thumping of heart, breathlessness, dryness of mouth, tremors, cold limbs, etc.
Fear resembles anxiety, but fear occurs in response to a threat that is external and is known to the person. In anxiety, on the other hand, the threat is unknown, vague and internal. While fear subsides by itself once the threat is over (for example, examination), anxiety continues to linger for long periods.
Psychologically, anxiety produces confusion and interferes with learning; the perceptions and their interpretations are altered. For example, an anxious person may feel that someone approaching him will harm him, even if he is actually approaching him to seek help.
