Should I avoid taking the Federal Unsubsidized Loan?

Accepted into my ED school and received my package. My predicted family contribution (I only live with my mother, whom I’m dependent on only) is about $1,900, after calculating work-study, Federal Subsidized Loan, Federal Unsubsidized Loan, and Federal Perkins Loan. I’m a financially need student (the school’s financial officer even said that my school’s grant is the biggest he has ever seen) and want to avoid this unsubsidized loan ($2000) from accumulating over the matter of four years.

So will this if I take this approach, will my family contribution raised to $3,900 after calculating an additional $2000, in order to avoid the unsubsidized loan. And I will get the $2000 from family members.

If you get the 2000 from family members, you must include it on the FAFSA next year

Will it affect my EFC or grant from the school if I receive $2000? I just think that this is a good approach to avoid summing up a value on unsubsidized loans.
