Can anyone recommend any resourses?

My Mother had breast cancer 11 years ago, we thought she was in the clear, she had been having stomache problems, as it turns out the cancer has returned quite badly.  My Mother leaves in California, I live in Washington, I do have other siblings in California, however my sister has been caring for my Mom, and has now exhausted all of her vacation sick leave ect. She has a high profile job. My brother leaves in Nevada, has two small children, and is a Highway Patrolman,

My daughters are older, my job, is just a job, I work part time at, but I can not afford not to have it, we need what little income I make just to make it.

There is no money for nurses, and although they told my Mom she has about a year, they can't yet term her as terminal.  She has a feeding tube and a draining tube, she often has had problems with these, so she can't be alone.  What do I do?

Thank you anyone. I really need some help. Is there any govenment programs are anything?  That would allow me to take care of my Mom for a few months at least?
