My father is dying but I’m ln odds with him

Hey, lm really in need of advice here. My relationship with my father was never really well all he cares about is my grades and what I’m I doing and I was bad at school and recently I dropped out of college.
I have a lot of hate for him but when now I see him dying I’m afraid that I’m gonna regret not trying getting things right with him, but in the other hand I can’t handle his presence I hate him so much.
What should I do.
