Call the passport hotline and explain your situation. If they're not helpful, take your application ID (which I think you can get from the online status check) to a passport center closest to you ( http://travel.state.gov/passport/npi...ncies_913.html ). Try to make an appointment, but if you can't, you'll probably be allowed in anyway with proof of imminent travel. Explain your situation to them, and they should help you.
