yeah, don't stress too much! if it's your first competition then just go out there to have fun. just make sure you know the rules, do a good warm up before, have all your gear organised, and eat well beforehand. i love competing, it's a huge adrenaline rush, and you always make good friends. just make sure you don't talk to people in your div before you compete! some of them, unfortunately, try dirty tricks, and it's harder to fight a friend.
