I hope and pray that the infection clears Amy and that her strength picks up. It's a very difficult time. Try to make the most of this time with her and although the temptation is to run around talking to doctors and nurses and doing various jobs for your Mom (and that's important too of course), do try your utmost too to just talk to her and hold her and just be with her in case the infection doesn't clear or she doesn't pick up strength. This time now is precious.
Pain management is vital at this point so if she is in any pain or discomfort then that is unacceptable and staff must intervene. You might consider talking to a hospice team even just to discuss symptom management. They are so amazing at ensuring that patients are pain free and relaxed. It's something to consider. I don't want to scare you. I know the word 'hospice' is not an easy one to hear but it's never too soon to contact them and they are so amazing at helping people with such serious illness.
I'm thinking of you Amy. Your Mom is blessed to have a daughter who cares as much as you.
"The friend who can be silent with us in a moment of despair or confusion, who can stay with us in an hour of grief and bereavement, who can tolerate not knowing, not curing, not healing and face with us the reality of our powerlessness, that is a friend who cares." [Henri Nouwen]
