Is it normal to cry after your university chem midterm?

Im a pre-med student and i just wrote my first chemistry midterm and I had studied a lot and was not nervous at all going into it. The questions they gave us were written so different than the ones we did for practice out of the text book. It was like they were intentionally trying to confuse us. Anyways I'm pretty sure I failed horribly and have spent the day crying. Does this ever happen to anyone else or am I the only one who cries over school?
