Everyone experiences anxiety from time to time – something specific, like going down into a dark cellar where you know the Book of the Dead is waiting,
or, in a more general sense, trepidation about what the future holds. Some people are gripped by powerful fears when confronted by quite normal everyday situations. For example, sufferers of agoraphobia frequently have panic attacks when caught up in a crowd.

The symptoms can be dramatic: palpitations, sweating, shaking, blind panic or fainting – even leading to death. Another anxiety disorder frequently encountered can be described as social phobia. Those affected fear above all situations in which they become the centre of attention in a group. They begin to stutter or turn red. In order not to avoid embarrassment, social phobia sufferers may become recluses, shying away from human contact and staying at home.
