I am so sorry to read this. I have no idea what you are going thru, as I still have my entire family, including my elderly parents, but I can imagine you are all devastated. And I know everyone says it, but, truely, she IS at peace now.
We had to have a wellness check done once, for my stepson, but thankfully, they got there in time. He tried to commit suicide. I wish your wellness check had ended on a happier note.
