I went through a very painful experience with my father who died a very slow painful death from wegners granulomytosis, my mother made me stay and watch with her until his last breath.
It destroyed me for years.
My mother now has MM at 85 years old and i won’t be watching her till the end, I am here for her now but i will step back at the appropriate time .
You have to do whats right for you at the time, i assure you my father was unaware and not thinking “where is he?”
Tell your sister that she did the right thing and may even be in a worse position now if she had stayed , we are all different.
