My question involves court procedures for the state of: Missouri

Hello. I was sued by my landlord (apartment) because I was unable to pay any of my bills due to job loss. I had previously talked to him about it, but he wouldn't even listen to me, and just dismissed me before I could even finish talking to him (He said "Sorry, too bad."). So, long story short, I went to court on the 11th of February, and basically said I knew I owed the money, since it was true, and was given a consent judgment in the amount of $820 (2 months rent that was past due), and $180 (Attorney fees).

Here I am, 1 week later, and I still have no job (still working on that), and am unable to even make any kind of dent in the $1000 dollar judgment against me. I am worried that I will get sued again or something or that they will arrest me. What can they do to me??? HELP!
