I am worried about my upcoming court date. :(
I wish I could relate, but I've never had to go to court. I hope it goes smoothly for you. All I've ever heard is to dress appropriately and to speak as respectfully as you can as possible. 
Yea that's what my attorney keeps telling me. I don't want to have to pay a large fine.
I hope for your sake that you don't have to, either. But this doesn't have to define you. How you respond can, though. If you're mentally tough, it will be a bump in the road. I guess do whatever you can to maintain healthy focus.
