Panic is part of the 'fight or flight' syndrome , and so is an essential part of our defence system.
Most of us will have panicked with good reason at some time. The traffic light goes green, we start to cross the road, a car approaches fast and makes no sign of braking. To panic in this situation is normal - we run, and fast. But what if a perfectly harmless everyday experience creates the same response - or worse, if you experience panic for no apparent reason and completely without warning. Anxiety can contain is a long list of symptoms, and different people will develop different patterns of symptoms.
