hi mica, you're in a lot better position than many people here who are simply stuck. You still have 2 years to burn so don't be stressed so much.
Nice job on your academics. You will need those achievements no matter what so please don't feel its wasted
With that said, I am unaware of full scholarships for undocumented students. However, there are relief funds for students that may have been sponsored by cultural groups. I know Mexican / Hispanic groups have their own pool of scholarship money awarded to undocumented students. That will require research on your own...
Good luck.
