Help for my mom with brain tumor

Two weeks ago we were a normal family, living a quiet life. One day mom felt dizzy and past out at work. After some recommended investigations, I found out my mom has a brain tumor - Glioblastoma multiforme, fourth grade. With the money we had saved, we managed to do a first surgery, but now mom needs constant treatment, chemotherapy and radiation to be healthy again. And all these cost a lot of money I don`t have and can`t provide. I am 24 years old, I am a full time employee and I am afraid for my mom. I am trying to do the best I can for her. I know this will be a long and hard journey, so if among you there are people who want to join and help us in our struggle, that would mean a lot for us.
