Is her time getting close?

I have an 84 year old grandmother who had stage 4 copd. Has had it for a while. Then right before christmas 2016. Her doctor. said she has Conjestive heart faliure and to see her heart doctor as quickly as possible. So in January I told her to the heart Doctor and they gave her a real bad report and that things do not look good for her.   She talks about her death often and how she wants to go home.  we have gone through her personal stuff all most everytime I go there. Any thought ?
