My question involves criminal law for the state of: Wisconsin

Hello Friends!

Okay so, I was charged last night with possession of thc and paraphernalia. This is my first offense of any sort and I am looking for advice from you! I am majoring in Education and have a strong love for kids. I volunteer, and work with kids. I am so worried about this effecting my life. I have a court date set for November. I am thinking about pleading no contest and talking to the judge about the fact that I work with children and that I know I made a mistake but I am young. I don't really know how it works in court, though. Do I get a chance to talk? Do I ask for it to be expunged? Should I get a lawyer?

If anybody has anything to say or advice to offer I would appreciate it so much. Thank you!
