Retail Theft In Illinois

I'm 18 years old and it's my first offense. I stole $57 of stuff from Target, including alcohol. Since I'm under 21 does this add another charge in addition to retail theft?

My court date is in mid January.. What I'm wondering is if it is going to negatively effect me if I go to the court without lawyer (plead not guilty and request a lawyer). I'd like to show up w/ a lawyer, but I simply do not have the money. Is it possible for me to request a public defender before the trial so I can show up with a lawyer?

Also, will I be recieving any mail regarding the case from either the court or the store? Will the store send me the civil demand before or after my court date?

Thanks a lot.

I mainly just want to know if it's possible to get a public defender beforehand.. And who I should talk to about this.

Call the courthouse and ask. I have heard of some who do get public defenders before court

Thank you.
