I just bought a book on self esteem and it calls your inner voice the critic. I haven't finished it yet and only on chapter 2 but it has helped. Chapter one described why your inner voice berated you and it's continuous talk is reinforced. It had an exercise at the end to write down critical statements your inner voice said and why it says it. Chapter two is quieting the critic and it so far has helped. The book is called : Self-Esteem: A proven program of cognitive techniques for assessing, improving and maintaining your self-esteem. I recommend it and I'm only on chapter 2.
