I'm sorry for your loss. I feel sorry for the poor woman.
Thanks for posting this. I found in the last few months after moving clser to my mother that she has been drinking again, in spite of the fact she's already damaged her brain with it in the past. Currently I am the only family that still talks to her and she's lost most of her friends as well. I get frustrated at times but if anything this reminds me of why I need to keep talking to her. Don't get me wrong, I don't enable her. She gets nothing but food from me. But I still talk to her and hopefully she will never feel so desolate and lonely that she'd have to do something like this.
