You can change. You can ‘come unto Christ, and be perfected in him.’
Feelings of worth come when a woman follows the example of the Master. Her sense of infinite worth comes from her own Christlike yearning to reach out with love, as He does.
Be patient with yourself. Perfection comes not in this life, but in the next life. Don’t demand things that are unreasonable, but demand of yourself improvement. As you let the Lord help you through that, He will make the difference.
