Write a letter to your mom telling her that you really do need some help with this issue, and if she doesn't see this as a concern still, I think you go back to your school counselor, and ask her why you cannot get your parents to help you.

Keep reaching out for the help you need until you get a responsible adult to listen. Try to stay calm, and in control, as 13 is hard enough without full support.

That you have reached out, is a great sign.
