I did the same thing. If you need, take a day off, go do something else more fun for a while. Then, start questing. Check out zone guides for where to go, and download metamap (or some other coordinates / map mod) quest helper, and if you want, quest announcer.

I went from about 44-55 with quests, and it's quite fun actually. More fun that power leveling with a pally (I did it from 8-42)
