My mum has cancer, diagnosed in December and awaiting treatment. She lives alone, and usually works a minimum wage job, but has been on statutory sick leave. With the cost of living, like many, she's been struggling with bills and food, and I've had to lend her money so she can make ends meet. She gets benefits, but there's still a shortfall each month.
I have a sister who lives in Dubai, who is getting decent money (she's just back from a 3 week luxury holiday and has booked another). Despite me being a full-time student with my own children, my sister offers nothing. My mum approached her for financial help (a loan), and my sister she says she can't afford to help...
At the end of the day, she's my mum and she's struggling, so I'll do all I can to help her. But the amount is creeping up (currently over £500, so not an insubstantial sum). I'm feeling so resentful of my sister offering nothing, and if I receive one more holiday photo from her - I may scream!!
Am I being unreasonable to want to distance myself from my sister, given how she's behaving?
