MI - I think GGG is right about it being a lot more complex if your relationship has been complicated and not a "normal" mother/daughter relationship (whatever that might be). I think you probably begin to think about the mother/relationship you wish you had had, which is harder. And there is no law that says you have to like your mother. I wish I liked mine more. There are occasional flashes of likeability, when I think "Oh she's not so bad" and then something utterly awful, that cancels it all out.
WAF - that is very sad and I am not sure how you handle such a meeting. When my friend died recently, her BFF, who had seen her a few weeks before, said they both knew it was the last time, and cried, and having got that out of the way, it felt cathartic - they could move on from there, rather than it being the elephant in the room that no-one was going to mention, and had a nice gossip and chat about old times.
