help sammy save up to move out

hello! i'm sammy, a typical 19 yr old freelance artist and full-time college student. i've been living with my aunt for over 6 years now and i've recently been having my hard-earned money sucked out of me. over 6k has been taken from me due to me turning 18 a year ago. i am now under the 'you owe me' card and is holding me buying a car from her, as well as her spending so much money on me as a CHILD over my head.

i need the funds to start saving up to move out into a decent apartment or hopefully have enough to be placed into a roommate situation to cover a few months of rent. i cannot take the narcissism and borderline abuse and being used as a human ATM any longer.

all funds will be put into a private savings account my aunt doesn't have access to and be saved up over time to afford whatever i can.
