Doug,
My perspective is that we are to love ourselves since we are made in the image of the Almighty. To hate yourself, yes, would be sin. But I wouldn't fight that negative belief with a negative. If you are loathing and hate certain things about yourself, remember, if you truly know Jesus, you have Him living inside you. He loves you so much to stay with you wherever you go, for good and for ill.
When it comes to 'hating' family or self, as it was taught by Jesus. Jesus was reestablishing the divine order. God is first. If anything comes above God, you can't be Jesus' disciple. Hating, in the gospel context, is to 'love less'. If you don't love your parents less than the Almighty, then you can't truly be Jesus' disciple.
Also, your old nature died on the cross with Jesus. You are made alive in Christ. I don't have the belief, as some, that we are wrestling with our old natures. Instead, we are wrestling with our mindsets to demonstrate Christ within us.
Bless you and hope the Lord opens your eyes to show you His expressed love in Jesus.
