Panic attacks

I never knew what panic attacks were. I was such a chilled out person during exams. But this one time I had loads of tough classes to take in undergrad and I had back to back exams. In one of the exams I was expecting high or low 90s but the real score was a disaster :D And right after finding score I had another exam for another class and that time I started to get panicky, It was soo severe that I had to leave the hall in the middle of the exam to go out and breath and calm myself.

And since then I get them when I know howmuch the task means to me. I can't help it now. Only I found was to busy myself into anything other than books right before the exam.

There are whole bunch of Anxiety disorders. Whole wide category depending on the criteria and situation. Panic disorder/attack falls under such as per my understanding but the symptoms for anxiety attack and panic attack are the same. Triggering factor and physiological effects.
