No worries, when i first went to uni i took far too much ! Food wise, my parents bought me a basic larder of stuff, like pasta and tinned stuff then when i got there they took me shopping to fill the fridge ( or my part of the fridge anyway !)
Take your books and folders etc; laptop and dvds u want.. clothes obvs ;-)
erm... photos ! PHONE CHARGER is important lol x But anything you do forget don't panic, shops are everywhere and new friends you'll make will help you out until you get what you need x
