Dixie,
What you have to do is contact a passport agency I am sure there is one in New Orleans and make an appointment. Just google passport agency Louisiana. If you can show that you are travelling within two weeks, they will give you a passport the same or next day. You need to fill out the application, have your old passport if you have one, two passport pictures and a birth certificate and other ID. It costs close to 200 for the expedited processing but you get is asap. Good luck.
