Unfortunately, you haven't given enough information to answer your question. There is a difference between being sued (which is civil - the worst thing they can do is get a judgment against you for money or get an order requiring you to do/not do certain things with the page) and being charged criminally, which may result in you having to pay fines, serve jail time, and have a "permanent record". You should contact an attorney in your area who practices both school law and criminal defense, and quickly. Your rights are easier to waive than you think, and you want to be sure that you do not take actions that could make your problems worse. If you are a minor, I would suggest that you talk to your parent/guardian about the situation, and explain to them why it is so important for you to have competent legal counsel.
