What can I do? Help me!?

We have parent teacher interview soon and I am really nervous. I hate this new teacher and for some reason I am always getting into trouble. Parent-teacher interview is coming up and I am not sure whether it is only based on academics. Up until now I have had good parent interviews but i'm not so sure this time. Also there was this one time where I accidentally kicked someone in the balls and I got in trouble. I got a detention but because it was on the last day of term it expired and I'm not sure if my teacher will mention in or not. If she does, my parents will be really mad at me and I will get into HUGE trouble.
