Got caught shoplifting. first offence. 19. what are my options?

Do your time. Pay for what you have done. No need for a lawyer when you're clearly guilty. Although, when I was 17, I was caught shop lifting with over 200 bucks worth of merchandise. Since I was a minor, I was given a second chance and regret ever even doing it. You made the mistake and now have to pay for it. Thieves get caught eventually. As far as jail time, I don't think that's likely.
