No one should have to apologize for being him/herself. This includes NTs.
I have explained in other forums here at WP that acceptance of self is a crucial part of self healing, and growing (though in not so many words). I think a person knows when he or she is doing his or her best.
So I will say this here. Sometimes we wonder if things could be different. But we wouldn't know this anyway. What would we have to refer to?
