Helping mother to get home

My mother is in Brunei for almost 5 years now. She is working hard for us to study but we (brother and I) weren't able to finish our education because we need to take care of my grandmother and uncle who suffered from stroke. They now passed away. We want our mom to have a vacation but she told us that she can't afford for now. I know that it's not a big deal for some persons. I just want to be with my mom.
