Can I beat a student loan lawsuit while in still in graduate school?

I am a student in a doctoral degree program? One of many student loans taken in undergrad program was past due $6000 plus interest. I was in process of going back to school for pharmacy. I applied for forbearance/deferment but the loan was sold from Bank of America to AES to Terri. I repeatedly told the student loan people I about to enter school but they filed a court proceeding in September 2008 and I enter school full-time in August 2008. I am not working and have no plans on working while in pharmacy school. I want to pay when I leave school. I would want the interest to accrue until repayment, as stated in my promissory note. I believe the lender or current note holder, intentionally not let me go back into forbearance. I am currently trying to defend my self in court from another state while in school. But I have made 2 filing on my own. I have even tried to request a dismissal. I filed affirmative defenses and now they want me to file admissions. The lawyer had made up all kinds of crazy request and asked who is my record custodian etc. I think I am over my head. I am considering contacting the lawyers office. Any advice? I thought if I am in enrolled in school full-time....in a degree seeking program....I cannot be held responsible for loan payments. Note this is for private loans. I have only taken private loans for undergrad. I am currently taking federal loans for graduate school. I had no problem getting those loans. For my first year of study. HELP PLEASE????
