"what should i do?"
Are you in high school? If so, if you're really good, you'll most likely get a scholarship to a relatively good college. Make sure to focus hard on your studies, because a better school often requires good grades and other things. Try working on being well-rounded. Volunteer, pick up an instrument or two and join some clubs if you have time. This will get you into a good college for cheap, and you can play football in college and then go on from there. Most professional athletes weren't financially stable growing up, but they did work hard in all subjects.
