Is it normal to think i owe more to my father than my mother?

Each year around mothers day I listen to all the talk about how we owe so much to our mothers .. I can't help but to think my father did more to shape me into what I am today than my mother ever thought about doing. Don't get me wrong I love my mother, but appreciate and respect is harder to come by. I do believe she is certifiably insane, and I think my success has come despite her rather than because of her. I do think I owe alot to my father and appreciate everything he did for me and still does for me. I feel like my relationship with my mother is very one-sided, she only wants money etc from me and I can't count on her on those bad days when you just need someone to talk to.. But my father I can!
Is it normal to feel like I don't really owe anything to my mother?
