well depending on when u got caught..if it was about an hour or two call her up and be like listen mom i was just sitting thinking about what happened..and how i screwed up...i thought it was nothihgn casue all these poeple i knew were doing it but obivously if i was scared of u knowing then it has to be a big deal or a problem...say u dont think u have a problem yet casue youve only done it once or twice..but u think ur going to go talk to the councleor at school to talk about your "problems" and find out how to stop "peer pressure"
