yes, it's the exact point. Surrounding persons can't change your thoughts completely as long as you don't want want to, it's always the first step which is hardest, I am sure once she gets on the first step everything will fall in place itself .
But until then, you, your family has to be with her. Usually if anyone is like this, out of anger, frustration or emotions people say... Umm... Like she is not in her right state of mind, but I would suggest to not say like this infront of her, as she might be very sensitive right now, it can hurt deeply.
If ond is gone, we can't change that but we have to show the love to the one who is with us.... Make her feel that she has many other person to take care of as well as who takes care of her.
