Can I use another relative information to fill out my FAFSA?

So my mother is a RN and last year she made almost 100 grand, and as a result of that I didn't get any grants and I only got a small amount of subsidized/unsubsidized loan. The thing is she refuses to give me with any money to pay for college. So I was wondering if next time I could use my aunts tax info for my FAFSA, because she works at wal-mart and that way I would get a lot of grans and loans to pay for college. Should I file for myself next tax season? PLEASE HELP!
