Hi,PecaS...Hope you are OK.I see that you are going through the anger phase of grieving, You'll start questioning everything as well, It's perfectly natural.
I know, it is awful the way some people treat your deceased loved one's body. I decided that I wouldn't be there when they took my Mum.
Hope you are coping ok with funeral arrangements and all that. I am also glad that you had a sign so early from your Mum.
Take care and just go with the flow for now.
