Anybody ever been to court? If so tell me your experience

Okay I'm a 17 year old girl living in the state of Illinois. Good kid, excellent grades, etc. Up until April 14th I've never been in any legal trouble.  Long story short, me and a girl got into a fight on a school bus & I ended up pepper spraying her. I'm defiantly paying the consequences for doing so, I ended up getting expelled from school & now I have to go to court. Has anybody ever been in a situation like this? If so what were your consequences, how was your court date, etc
