第二篇when fear takes control of the mind
a panic attack is a sudden feeling of terror.usually it does not last long，but it may feel like forever.the cause can be something as normally uneventful as driving over abridge or flying in an airplane.and it can happen even if the person has driven over many bridges or flown many times before.a fast heartbeat.sweaty hands.difficulty breathing.a dizzy feeling.at first a person may have no idea what is wrong.but these can all be signs of what is known as panic disorder.the first appearance usually is between the ages of 1 8 and 25.in some cases it develops after a tragedy，like the death of a loved one，or some other difficult situation.
in the united states，the national institute of mental health says more than two million people are affected in any one—year period.the american psychological association says panic disorder is two times more likely in women than men.and it can last anywhere from a few months to a lifetime.
panic attacks can be dangerous—for example，if a person is driving at the time.the chesapeake bay bridge in the state of maryland is so long and so high over the water，it is famous for scaring motorists.there is even a driver assistance program to help people get across.some people who suffer a panic a~ack develop a phobia(惧怕病)，a deep fear of ever repeating the activity that brought on the attack.
