Support a 72-Year-Old's Medical Journey

I am 72 living on social security fixed income. My health is not good. I am type 2 diabetic, my kidneys are not functioning I am on dialysis, I just had a double bypass open heart surgery. It is hard for me to get around and I can’t work. I tried to get disability and food stamps but I was denied both. I am trying hard to pay bills but I am struggling. Medical bills are high, I have to pay bills by credit card and my credit card total is out the roof. Please I need help. Thank you in advance!!
