Family Desperately Seeking Help

Hello. I am a 31 year old mother from NSW Australia. We Desperately need help to buy food and other household items. I have been calling every charity available in our area for the past couple of weeks but, I have found no help at all. By the time i got off hold, every place in town was closed. I don't have any family who are able to help us, my mother passed away close to 4 years ago and my father is Terminal, We are not sure how long he has left. My father has brain and lung cancer. We have been traveling the 8 hours to see him as much as we can but its nearly imposable to get enough money together to make the trip. The last few months have been very tough. I don't know what to do Or how we are going to survive. Its tearing me apart that i can't provide enough food for my family and I have no where else I can turn. I know theres a very good chance that no one will help me but, i had to at least try! Any help would be greatly appreciated, I wouldn't even know how to begin to express how grateful we are for any help. Thank you for your time. If anyone has any questions please feel free to contact me.
