Financial help

My mom uses a bank loan to help us the siblings for our education. But now she's old and not working, she can't pay the debts. With my salaries also I can't help her that much since the interest kept increasing. My sisters and brothers are still schooling though. Helping her is the only way that i can repay her. I know she went through a lot during thhe divorce of my parents and my dad didn't even care about us.
