Hi @Meex05 , sorry to hear this news, that’s really tough.
Although my cancer was stage 2 not stage 4 , I found my sister ( she is my only sibling and we are very close although she lives an hour away) a great support and help over this last year ( diagnosed August 2020).
She rings me every day and we totally “ get” one another so there is nothing we can’t say to one another, no awkward moments .
Everyone is different , but I found just having people to talk to helped me a lot , and also to talk about things OTHER than cancer was helpful , including having a good laugh ( to balance out all the good cries).
it’s hard if you can’t physically be together as that would be ideal, but staying in touch by phone ( or zoom etc if you are more of that persuasion)
Is one of the best things you can do for her.
Lots of other helpful advice from the ladies above too.
Take care and sending you virtual hugs.
