Walking debit card

Dad treats me like a walking ATM machine. Expects me to pay for everything and never offers to pay for anything even for his personal stuff. I don't know if this is common but I feel so shitty.

He also treats me as his own personal maid and driver, never wanting to do anything for himself. I just want to separate myself from him but i'm his only family left.

I'm so tired. I don't know what's the purpose of living anymore.
