M.P.
The only people who can reliably answer this question is the court in Atlanta or an attorney who practices in Atlanta and is also familiar with your case. I urge you to call the court directly and talk with them.
If you're wanting custody, I suggest that you call the court immediately. You not showing up will cause the other person to win by default. If the court can't accommodate you, perhaps by having you present via telephone or computer, then I suggest that you may be able to hire an attorney to appear in court for you. I believe that you'll need to find some way to have representation in court.
