The answer to your question is yes you can sue for slander and iif someone writes something bad and you can prove its them then you can sue for libel. Libel or slander is when you take someone and say bad things about them that make people think of them differently and it has to effect there everyday life. But the chances of this succeeding are very little you have a better chance calling the police and see what course of action they suggest..also a minor can sue but it must be done through the letigimate guardian...and don't be scard to go to school keep you head high and don't listen to what no one else says
Hope this helped you a bit :)
