Annoying, but not that hard to fix. You have two or three choices. If you made a backup, you can restore that from recovery mode.
You could go to download mode and flash a stock ROM onto the phone, then root it again.
Or you can go with a custom ROM as the poster above suggested. You generally need a custom recovery for that, so you'd go to download mode and install a custom recovery first. Followed by the custom ROM. If the custom ROM is a tar file, you'd also flash that with Odin in download mode. If it is a flashable zip file then the custom ROM would be flashed after you boot to the custom recovery mode first.
If flashing a stock image, ensure that it is a version 4.3
AT&T image. Trying to flash an earlier version will do bad things to your phone.
