Am I fucked for grad school

It looks like Im about to fail a 300 level physics lab course for an extremely retarded reason. I can retake the course next year and presumably offset the damage it has done to my GPA but that F is gonna be burned into my transcript for all eternity. I have read online that gradschools dont really care about an F if its in a first or second year class or unrelated to your major but this is a core third year class. Is my academic future completely fucked?
