You previously indicated that you planned to get a lawyer. If your county offers a diversion program for shoplifting, your lawyer can advise you of that option - a diversion program would allow you to avoid a criminal conviction. If not, discuss "HYTA" with your lawyer, another way younger offenders can avoid getting a criminal conviction. If this remains your only criminal conviction you would eventually be eligible for expungement, but it's better if you can avoid the conviction in the first place.
