You should consult a local attorney - but at age 18 your rights change.
Under the rules governing the conduct of attorneys in New York it may be necessary to remind you that this answer could be considered attorney advertising.
Generally, in your state the child support obligation ends when the child reaches 18 years of age or graduates from high school, whichever occurs later. I believe a GED counts as graduating from high school, and now you are 18, too, so I don't think child support will resume unless there was a private agreement to extend it beyond the minimum statutory requirement. Good luck!
