Acknowledge to yourself that it’s hard to watch and hard to make decisions for her care. It’s brutal. If she hasn’t yet, but still can talk with her about the end of her life. I was able to imagine my mother at 60 standing at the foot of the bed next to me when she was in her eighties. I could check in by asking her what she wanted me to do. The message was always to follow her instructions and not to let anyone push me or guilt me into changing the plan. Be kind to yourself.
