Double Whammy

My name is Rozel Swain, a single retiree and lifelong resident of Tampa. 10 months ago I was diagnosed with peratennial cancer. After surgery in January, I began chemo. Then in May, I received a second diagnosis of liver failure. That's the Double Whammy.
I live on a fixed income of $1642 monthly, but my mounting copays run close to $1,200 monthly. With the new diagnosis, that will increase.
I live modestly in a retirement community where my rent is only $500 monthly. My daughter and other family members have have helped me, but I can not continue to borrow from them. 
I'm not looking for a vacation or to make a wish. I simply am seeking assistance to meet my living expenses and whittle away at my medical costs.
Thank you so much for anything you can do to help me.
