I'm going to court, what is it like?

i'm a 14 year old girl and i was caught shoplifting from a chain retail clothing store the other day. it was the scariest experience of my life. the store said if my dad picked me up they could release me but my dad wasn't picking up the phone so the cops came and handcuffed me and brought me to the station where i waited for hours for my dad to come. they said it'll be removed from my record once i turn 18, but i just have to go to court in a couple weeks. what should i expect from the court?? are there going to be a lot of people?? will i have to sit up front and make a speech?? i'm so scared. pleaes don't lecture me, i know what i did was wrong.
