I still can't get hold of the only person who can authorise an extension to the deadline, so I've kept at it to the best of my ability.

I've called the university to let them know what's happened and I've now laid down for a few hours rest. I've given everything this broken body has, my poor muscles hurt terribly and my mind has seized up. There is nothing left.

I'm going to get some sleep and a meal, then will see what I can do this evening.
