I'm really behind schedule with college?

So my parents are paranoid and thought that i would get beat up in public school or something. They're solution was to send me to a Christian private school. This school sucked. They have no athletics programs or any extra-curricular activities really. We had no counselor to tell us about the PSAT, SAT, or ACT. So me and the only other senior are a bit lost at the moment. Im late with registration but luckily I found a few schools. The only thing now is that I need financial aid. It's June and school starts in August I believe. I haven't found any scholarships that apply to me and if I have, the deadline already past. Today is June 13 and if you know of any scholarships whose deadline hasn't passed, please share them. I have 4 other siblings and my dad is self-employed. I really need help with this.
