Not sure where you are - but have you thought about
getting Hospice involved? Also, what about
a death and dying counselor - someone who will help ease her through this time, and give you the tools you need to deal with her anger. I would highly suggest talking to the doctor about
something to help when she's aggitated (Xanex or Ativan), also an anti-depressant and a sleeping pill.
My husband dealt with a lot of depression before his liver transplant (I honestly didn't think he would make it to transplant) - he was taking Lexapro for depression and Ambien for sleep.
Best wishes to you.
