Your father is about to die and your mother mother will sprial into a deep depression, and she's not going to be able to help you with anything when you get older - not getting your GED after this homeschooling doesn't work out, not going to college, not finding a job or getting a car or any damn thing. You're gonna be alone in trying to figure out the entire world that you were so sheltered from for your whole life. So insist on going to public school. Insist on it, and go everyday, and study, study, study. You're smart enough to get straight A's, to get a scholarship and go to a good college. You're on your own after Dad dies, so start putting yourself first as soon as you can.
