I don't want to see my dying father
Why do you not want to give him one last visit?
I want to remember my dad when he was in good health.
I agree it can be very unsettling to be with a parent who is dying, but you're all they need in their final moments. You might regret not being able to say goodbye or being there for him in his last moments.
He deserves this, he was the worst dad ever.
I still think that you should go see him, I know it is uncomfortable, but you might need the closure. Otherwise you might have regrets later in life. Who knows he might apologize for being a bad dad.
