How can we distinguish if our devotion to work is ocpd or not?

i often get preoccupied with something that i do, for ex. when i was at college i used to occupied with my exams, and study hard to p them so that sometimes i even avoided leisure activities just to study. and no, my parents didn`t force me to study that much. was i simple perfectionist or more like ocpd? and if yes, is it curable?
