My mom won't help me complete my CSS profile

Chapel Hill meets full need, I’ve already been accepted, and fafsa didn’t require that I provide asset information. At the core, my mom is unwilling to give me the information because she doesn’t want me to go. I’ve been aware she doesn’t want me to go to college all my life, which is why I have given my all in school to be eligible for the most amount of scholarships possible. I’m number one in my class, class president, and I’ve taken dual enrollment courses so my chances of getting other scholarships I’ve already applied for is pretty good, but I want to be able to qualify for UNC’s full aid and I’m afraid I won’t be able to without this information.
