Have been diagnosed with nerve Sheath tumour.

Hi, my name is Inacio cossa.
I have been diagnosed with malignant peripheral nerve Sheath tumour on my right leg. A few weeks later I was informed that tumour has turned into a cancer. And it has spread all over my lungs, my abdominal area, my right shoulder and probably to my lower back area (spine).

I'm receiving chemotherapy every 21 days. I have to go through to 6 cycles of chemotherapy to complete my treatment.
Im concerned that I ran out of money and I don't have any money left to pay for my bills.
The tumour on my right leg forced my leg to drop. I can't move with crutches because of that I'm very limited with what I 'can do' and  'not do'.
I'm not working at the moment due to my current situation. 
This amount will be very useful for me in the future.
I'm not sure for a long I'm going to be in treatment. I was told that they probably will have to operate my right leg to remove the tumour.

I don't know what to do or what to say, but I'm afraid that I'm really going to need this help.
