While you are living in a doubled up situation (living with other people because your family cannot afford to live on their own).
Definition of doubled up
What is a double-up living situation:
Oftentimes students live in temporary housing situations with relatives, friends, or other individuals because of a loss of housing or economic hardship.
Unaccompanied youth (students who are not in the physical custody of a parent or legal guardian) more often than not find themselves living in doubled-up situations. These students should be designated as homeless under the McKinney-Vento Act.

When you are not in college you go back to your aunt’s house with your family. This means that you are not an unaccompanied minor, who is a homeless youth.
definition of unaccompanied youth
An unaccompanied homeless youth is a youth who meets the definitions of unaccompanied youth and homeless included in the McKinney-Vento Homeless Assistance Act (42 USC §§11431-11435, 2001; hereafter referred to as The McKinney-Vento Act). The Act defines unaccompanied
youth as, “a youth not in the physical custody of a parent or guardian” (42 USC §11434a(6), 2001).
This means that the youth is not living with a parent or guardian, and includes youth who are
residing with a caregiver who does not have legal guardianship and youth who are living on their
own.
The McKinney-Vento Act defines homeless children or youth as, “individuals who lack a
fixed, regular, and adequate nighttime residence” and provides a list of examples of living
arrangements that meet this definition (42 USC §11434a(2), 2001) (see sidebar on page 1 for the
full definition of homeless).
To be eligible for services under the McKinneyVento Act as an unaccompanied homeless
youth, the student must lack a fixed, regular, and adequate nighttime residence, and not be in the
physical custody of a parent or guardian.

If you were an unaccompanied minor, then you may be considered independent. However because you are with your parents, you must use their income/assets on the FAFSA.
