You think you've heard it, but really it's to hard to believe. That's how it was for me. I think deep down I was in denial till the day she passed...even then I didn't accept it for awhile. Grieving process I suppose. I'm so sorry for your news. My recommendation is to do what I wish I would have done and that is to say anything you ever wanted to say, be physically affectionate, and try to accomplish something you always wanted to do with your mother.
