Yuck, I know how you feel. Two weeks ago I came down with a wicked head cold that lasted exactly a week, with the runny nose part dragging on for a few extra days. The symptoms were exactly as you described yours. I pretty much went with lots of liquids + lots of rest, and it finally cleared up on its own. I don't know if you are able to take Sudafed, but that helped me with the stuffy nose part. (Real Sudafed, that is; the kind you now have to get from behind the pharmacist counter.)

Hope ya feel better soon!
