Consequences for teepeeing?!?

Last night my friends and i teepeed this girl who we HATE. But we didnt only put toilet paper. We chalked and said some really mean things and we put shaving cream and forks and syrup in her yard. We didnt do any real damage but we said some really mean things and called her a "barbie *****" and talked about how she has a hairy vagina. Haha. But she's saying on facebook that she had video cameras and that she went to the cops but i doubt it. Im realllllly freaking out cause i play volleyball at my school and i dont want to get kicked off. And on facebook she liked all of our pictures together and "poked" one of my friends that was with me. We're freaking out cause i dont want to get in serious trouble. Should we fess up?
