My mommy ❤️ died on the 27th April 2021 but she had been in hospital for about 5 days before dying there. From time to time her eyes were open and rolling a little back very quickly. She was on oxygen, no blueishness as they when people Start dying , her urine was reddish on the first day. The second day it turned normal yellow but there was very little urine in the bag. She was only on IV and I kept asking her if she was hungry . She only tried to say yes once. Other than that when I kept talking to her loudly , she would just look at me or sleep. Did I kill my mother in the hands of bad hospital doctors?
As others told you, she was dying. You did NOT kill your mom. I recently lost my mom too. This is a time of grieving for us.
I wish you well. Take comfort that your mom is at peace.
As to the urine, concentrated urine turns so brownish and rusty looking that it appears red-brown in color. The lack of urine was dehydration and the kidneys shutting down.
I hope the hospital personnel helped you with understanding some of the process; hospice often serves to do that when they are involved. I am so sorry for your loss.
Sorry for your loss
Find grief support for yourself. If she was on hospice they will offer counseling for a year following the death. Many churches also have brief support. Or individual counseling. There are online brief support groups available, as well.
