I'm an M1 at UIC-COM right now. Sadly, there's not many financial aid options aside from loans. The General Assembly scholarship is a great one in theory, but IL is so broke right now that my state rep decided to suspend the scholarship until the state's financial picture gets better - I'd check with your state rep's office to see what s/he decided.
Being Latina should help, I remember coming across several scholarships for underrepresented minorities. I came across them when searching for scholarships on Google and various scholarship sites, so they're not hard to find.
Aside from that, though, you're looking at loans. The Federal Stafford Loan has a limit of $8500/year, I think the Fed Unsubsidized loan is something like $35,000/year, and after that is the GradPLUS loan.
The finances suck, but don't let it obscure the fact that you're one of the select few that made it into med school. You'll be able to pay it back over time.
