I just don't want to be charged with anything im full time college student and I made a stupid choice and I will never do that ever again.
Criminals always whine like that when they get caught.

What should I do?
Start by looking for another job as I doubt that you have this one any more.

You may be given a "civil demand" letter requiring you to compensate the store. If you pay it quickly and quietly that may be the end of it since no police were involved.

Otherwise, all you can do is sweat it out and hope they don't involve the police.

Meantime, I suggest you not talk about to ANYBODY except a lawyer should you choose to hire one.
