Thank you for your comment
I had interpreted bad self- esteem as
 “Schools etc have inflated self-esteem quite artificially, with no reference to God, and from a secular point of view,” 
  I agree that
 “Our only esteem should be a natural one flowing from our divine filiation, that we are children of a loving, personal Father God, Who loves us and wants the best for us, the truly good”
I would add as manifest by His son Jesus Christ

 “Be ye therefore perfect, even as your Father which is in heaven is perfect”

This teaching can only be achieved in humility (St. Bernard-Humility a virtue by which a man knowing himself as he truly is abases himself)) to a base oneself before Our Father in heaven. We can only walk in humility before our Father in heaven as we are all continually dependent upon HIS mercy and it is His esteem that I humbly search for.
