HELP HIGHSCHOOL CREDIT?

okay so im 18 and im pretty much need 2 more years to finnish highschool. :( i went to private school in the 10th grade my parents couldnt afford it anymore therefore they did not release my transcripts and i got 0 credit for a whole school year and thats what messed me up ! but my question is is there any online schools (free if possible) or homeschooling or anything you know of that can get me to graduate within a year? or even a year and a few months. i was gonna get my GED but my father wants me to get a highschool diploma like everyone else but what he dont understand i really dont want to be in school when im 20 so if anyone know any schools that can help me with my credits please let me know thanks
