<human>: Condense the text into a few key points

Hi Reddit, my grandmother just had life saving heart surgery, but a month on is very depressed and wondering if it was even worth it. 

*She is a widow and lives alone, we try to visit her as much as we can, for example I went last night, someone tries to get there at least every other day, but it's inevitable that she spends large amounts of time alone. 

*She has always been anxious, and heart surgery is known to bring on depression as well. She used to fight it by doing things like work around the house, but now she either doesn't feel like doing the more simple things like cooking and the more heavy duty work is not possible because of the recovery and ailments of old age catching up. 

*I encouraged her to move in with my family to at least be around people more, but she doesn't want to intrude and inconvenience the family and is quite adamant about that. 

*She can't drive anymore so she's not able to take herself out either. 

*A nursing home is an option, but it's a radical change and very expensive.
<bot>: Basically I'm asking how can we find a sense of purpose and reason to live for someone who doesn't have much of a life anymore?
