My retirement needs

I am 72 years old and had planned to work until I die. Recent health set-backs find me with Stage 3 post Metastatic Breast Cancer:  narrowing of the spine at numbers 4 and 5 lumbar vertebrae:  Type 1 Diabetes and Rheumatoid Arthritis.  As a result of these recent health set-backs, I am unable to work as a San Francisco medallion cab driver, my profession for the past 24 years.  I have no retirement and receive very little in monthly social security benefits, to pay my monthly bills and expenses in San Francisco.  These funds will help me to survive, as my situation is quite urgent.
