I’ve just found this thread and thought I’d join in for some ideas/support hopefully.
I suspect this won’t be brief, but I’ll try not to bore you. I have 2 sisters (and a brother) who are both being treated for cancer currently. Both live abroad so I don’t get to see them very often, once or twice a year. My eldest sister (77) has been an alcoholic for most of her life since turning to drink in her 20s when she went through a difficult divorce. She’s been drinking ever since, through an abusive partnership which ended when her partner died, and has reduced the amount she drinks but has never given up. In the past 7/8 years she has been treated for lung, liver and breast cancer and is currently waiting for test results to see where she stands now.
I consider that we have a close relationship, although she’s a lot older than me, she’s godmother to one of my sons and loves my (adult) children dearly. She’s very religious (which I gave up many years ago). All my siblings and I are in contact and try to support each other, but we all have very different lives.
My sister is rude when she’s had a drink. She’s rude to me and to her very patient, quiet and kind partner. She has few friends. I remember once when my son was little she was aggressive towards him on one occasion and I didn’t say anything, but I remember deciding that I wouldn’t put him in that situation ever again. The last time I saw her was a few months ago, she was rude about my weight - I had put on weight due to heart medication I’m taking. She was also nasty and aggressive to her partner about something trivial and he didn’t respond. As on previous occasions, rather than confronting her, I decided not to visit again for a while because I would stay at their house and then have to witness her drinking and resulting behaviour. She has asked me to visit again while she’s in the UK having tests. I have never said anything about her drinking - it’s like we all know it happens and pretend it doesn’t and, being the youngest sibling, I’m still treated as the baby of the family and don’t confront her as she’s the eldest and is treated with deference and respect, mostly.
She’s having a tough time obviously, with her treatment, and I want to support her, but I don’t want to confront her and upset her as she has few people in her life already, but I wish she knew how much her behaviour hurts the people she cares about.
