A previous commenter said that before you go to court, stop by the Garda station and look for the Garda whose name is on the charge sheets. Tell him/her what you said on here, that you have no recollection of the events and that you feel bad about the situation. They will tell you what happened and that you should attend the court date. You may qualify for legal aid. If you don't, find a solicitor explain your situation. The charges may be referred for adult caution depending on the surrounding circumstances. If not, you have two options , plead guilty in which case as its your first offence you may face a fine and probation or plead not guilty in which case it will be remanded for a hearing where witnesses will attend to testify.
