I think Dr. Bob talks about this in his story in the Big Book. He felt bad when he was faced with the fact that he could not drink any more. He came to realize that he had abused the privelege to drink so badly, that he just wasn't entitled to do it any more. The consequences were just too great at that stage of his disease.
I think this feeling lessens with time. It has started to wane for me at 7 months and I hear this just keeps improving.
You are doing fine and just let the feelings happen. They are perfectly natural and understandable.
