<human>: Can you give me a shortened version of the text?

I still live at home while I finish studying while my older brother lives on the other side of the world. My mother has just had major surgery and will soon be recovering at home for the next six weeks (she's still in hospital atm). I'm taking a few weeks leave from my degree (final year grad school) so I can at home all the time to help her dress, shower, cook for her etc and I have no problem with that - she's my mum and she needs me while she's sick. 

The problem is that my brother doesn't seem to care at all what's going on. He's always been poor at calling regularly but I expected that with such major surgery he'd be a little more interested in how she's going or even how I'm coping. 

My dad died when I was younger and all my mum's family is interstate so I'm kind of it. I have a fantastic boyfriend who is so supportive and I really couldn't do this without him but he couldn't offer much perspective on how to deal with this stress my brother is causing me.

My brother has started at family of his own now and his wife's dad has been very ill - I understand he has a lot on his plate but how hard is it to respond to a facebook message once in a while so I know he's thinking of us? Shouldn't having a family of his own remind him how important the rest of his family is? Even with the support of my boyfriend, I feel very alone. Do I need to stop whingeing and just get on with it? Am I not understanding his perspective enough?
<bot>: my mother is ill and I am caring for her, my brother who lives overseas doesn't seem to be interested in what's going on and it makes me feel angry and sad and lonely.
