Panic attacks or anxiety attacks are quite common in young adults these days but they must not be ignored. It's mind/body's way of telling you that something is not right and you need to address it. There is some underlying condition, may be a conflict, fear, guilt, anticipation or something else which you may be trying to repress consciously or unconsciously. Psychotherapy/counselling will help you identify that concern and address it from the root.
