Thanks Mertex. Just been texting mum, nana has fluid build up on her heart and she's also retaining fluid in her legs. There may not be anything else that can be done for her. She has notified the other family, and they say they 'might' come and see her.
In other words, they don't care unless she is on her death bed.
Sounds to me that she is in bad shape, doesn't sound like the other family is that concerned, that's a shame, they may miss an opportunity to see her again while she's still alive. Does your nana live close by to where you live or is she like in another state?
She's about forty five minutes away in a hostel, but she needs to be in a nursing home. Whether she will make it there is a question in itself.
I think they do care, they just can't be bothered driving up to see her when she might be okay. They think a two hour drive to see their own mother is too much to ask.
