Patties cancer treatments

My wife of 45 years Pattie has been diagnosed stage 4 stomach cancer that has migrated into her bone marrow.
Chemotherapy wil start Monday the 6th.
She has been doctoring with 3 doctors for a long time with no one able to find out why she has been in so much pain. We admitted her to Chandler Regional Medical Center 2 weeks ago. A team of doctors did test after test and finally found the cause. I am looking for help for medical bills that her insurance will not cover. My only source of income is   Social Security,...and my wifes sick days with pay are coming to an end.

Thank you for any support
