After college, I'm going to cut ties with my father.
Why do you want to end your relationship with your father?
I can't live up to his expectations and he has been a failure as a father
I know you're upset, but it's mean to cut ties with your father. You should sit down with him and settle your problems.
I hate my dad, he's the worst.
Not everyone has good relationships with their parents and it's clear that yours with your father is quite strained. Cutting ties is permanent though, so having a conversation with him in an effort to heal your relationship is something I'd try first before making a drastic move.
