I don't know what to do. I don't have the money to pay it off. I don't want to appear in court either.
But it's not going to away on its own, so you have to do something. As LNR suggested, if you don't show up and they get a default, the creditor will begin post-judgment proceedings, which only means (a) more time in court and (b) increased costs to you and (c) certainly more emotional wear and tear on you.
Therefore, you need to file an answer. It doesn't have to be a fancy answer. You need to either contact the creditor before the court date (if you can reach them and they will talk to you) and work out a payment plan, or show up in court and try to talk to the creditor then (usually before you see the judge, there's a chance to make a deal). Be organized- list out your assets, your monthly income, expenses and be prepared to present a reasoned explanation for your settlement proposal. If most of your assets are exempt, and you have other reasonable expenses, the creditor may be persuaded to accept a payment plan you can live with. I can guarantee you it will be than what happens if they get a judgment, when the creditor tries to collect the debt (look at the posts on this forum that start with "help, they garnished all my money").
