Single mother with huge debts

My father passes away at the age of 51, leaving a debt of 500 000 SGD. He sent 4 of us to Singapore to persuade a better education due to lack of education system in Myanmar. I did not know our school fees were so expensive till i reached the age of 17. So i started working part time jobs to take some burdens off from my parents. After much hustling, I've finally graduated back in 2016 December. Then i started finding full time job in Singapore. After 3 months my Father has passed away. It was very hard for our family cause hes the only working man that supports the entire family. My mother has always been a house wife so she doesn't know much about work. Recently she broke down, told us that father left a huge debts and we have sold most things to pay off the interest but its no longer enough. The bank is threatening to take the only house we have left. I found a full-time job back in 5th December 2017, it hasn't even been a year. My pay is only 2.5k & i often send back 1.5k back to my mother leaving 1k for my house rental and expenses. So i barely can pay off the debt myself. My eldest sister got married and living with his husband, my eldest brother got married with 2 children and doesn't have a job. Only my elder brother and me are working hard to support my mother. Now this news came and we can no longer have strength to continue, therefore we need your help. Even if you are financially unable to donate, please share around. I appriciates it.
