Bankruptcy and Private Student Loans - NOT Federally Funded

I filed bankruptcy over a year ago. Last week I rec'd a phone call and then a statement from a collection agency representing a company that i have student loan with. I called my attorney who handled the bankruptcy. I told her that the student loan that I have was a private loan. She said if it is federally funded that it cannot be discharged. I called the lender, American Education Services, who told me that it was NOT federally funded. How do i make sure that this loan is discharged (without paying my attorney more money)? My plan is to dispute the amount owed on the statement that the collection agency mailed to me - On the back of the stmt in fine print, it says write to them within 30 days if I want to dispute. I don't have a copy of the loan papers or contract that i signed when i took this loan out in 2005, so i'm going to request that the lender mail a copy to me. This loan was for elementary and secondary education I believe that's how it was catagorized - i put my daughter at 15 in a boarding school out of state because she wouldn't go to school, ran away 5 times... just basically out of control. By the way, I live in Missouri (I don't know if that matters or not). Anyone have advise for me?
