attack is a sudden episode of intense fear
that triggers severe physical reactions when there is no real danger or apparent cause. Panic attacks can be very frightening. When panic attacks occur, you might think you're losing control, having a heart attack
or even dying.
Many people have just one or two panic attacks in their lifetimes, and the problem goes away, perhaps when a stressful situation ends. But if you've had recurrent, unexpected panic attacks and spent long periods in constant fear of another attack, you may have a condition called panic disorder.
Panic attack can come in agoraphobia, when there is fear of places where there is no exit, in crowds, locked places, travelling far from home….etc.
Although panic attacks themselves aren't life-threatening, they can be frightening and significantly affect your quality of life. But treatment can be very effective. Consult a Psychiatrist
and get remedy. All the best for you.
