Do I really have to like my father? I want to hate mine.
Why do you want to hate your father?
I feel conflicted about him because I also still love him and worry about him.
If your relationship with your dad is complicated, it is normal to feel conflicting emotions. You don't have to feel bad about wanting to hate him and still loving him at the same time; that is normal for difficult family relationship.
So I don't have to feel bad?
Many people have conflicting feelings for their parents so I do think the way you feel is normal for some.
