So sorry tro hear this dot - it is so sad.
I am a great believer in the concept of saying the right thing, or if you can't do that, say nothing, and just be there. It does work.
Remember, grief is not a competition - no-one is handing out prizes for the wisest coment or the saddest mourner.
Everyone will get through this in their own way - you must just be able to reach for each other when you, or your family feel the need.
And as this response shows, we are all here for one of our oldest AB friends.
Thinking of you,
