There is an old saying: "There are two type of people. Those who do regular backups, and those who wish they had." Unfortunately it sounds like you're in the latter group this time. Depending on someone else to recover/retore your computer after whatever disaster must have befallen you is not the way to go (as you found out!) When you get your old computer back, and also when you get the new one, make sure you put a strong backup strategy in place so you don't end up in this mess again.
