you poor thing, its so so hard getting over someone, especially if you never really even *had* her...i know im going through something similar
but one thing that struck me reading your posts was that your not putting the work into your resits and might fail. NO. in a way getting emerced in work and getting a focus (ie to get to uni next year) is a brilliant distraction from her.
also you only have one year left after two whole years of uni, dont waste the opportunity to get a degree for the sake of a girl.
things are difficult now ..and its even easier to feel lonely during summer when you dont have your bubbly uni 'family' around you but yu cant let this affect your whole life.
in cases like this i honestly think that one of the easiest things to do to ween yourself of somone, is to focus on some other girl...very very hard when all you really want is them, but i find its the best way as you have somoen to occupy your mind apart from them, you feel wanted by someone else and things suddenly dont seem to end at her.
summer is the perfect time for casual dating so i think you should get out there and look for a girl wanting something similar for over summer.
