i think your siblings are being very selfish
if they want to live abraod fine, but they then need to pay towards either having a carer, or putting your mum into care
come back and help care or cough up in other words
could your mum live with your nmc, or would that tip you over the edge?
are there no neighbours/friends near her who can help out by popping in daily?
let your mum complain and go into martyar mode - if you didnt pop in, she would be alone, and bet she thinks the sun shines out of your siblings arses as well!!
so i suggest not popping in, next time she calls and say no you are busy/cant etc, and see what she says
it is hard work looking after parents, but even harder in your case as you have your gorgeous dd as well as yourself being disabled and you have no help from siblings
sorry no real advice but didnt want to not reply
