When will it end?

My mother 83 diagnosed with pancreatic cancer in February hap the whipple and every complication along with it 54 days in hospital 30 days in rehab been home since , with a friend needs 24 hour care . I came back sept 1 when she stopped eating she has been in the bed due to diarrhea and she has neuropathy in hands and feet I was afraid she would fall so she's been in bed since sept 2 .. Started giving her morphine for pain she claimed to not have (but did) then last Thursday she stated hallucinating at 2am so they put on meds .. Her vitals are still good so hospice can't tell me when ..it's just very sad to see her laying in bed mostly sleeping can't suck on a straw so I drop ice water in her mouth , she doesn't understand why she can't drink it .. She never wanted to be in this state of mind and body, we are at a lose of why God hasn't taken her home .. I'm here at her home with my aunt her sister which has been a blessing getting to know her , she explains a lot of my mothers behavior .. We just don't want to see her suffer and wish she'd let go ..
