Bursaries

Going into university im planning on going away, my parents make too much for me to apply for bursaries I would think and they told me if I'm going away I have to pay for it. So when schools request to see my parents tax returns for the previous year, is that going to screw me over to applying for any busaries as i'm paying for the living conditions by myself? Or even anything related to financial aid, since my parents make X amount i probably wont be eligible??
