similar situation here. my parents told me they'll never offer me any financial support. i recommend reaching out to the FCRT and let them know my situation. i'm currently in the process of being declared independent as unaccompanied homeless youth. should be getting a lowered SAI and therefore more aid from FAFSA and UCSB themself. this may not be the help you'll get, but it's good to at least try and reach out.
