Husband’s leg amputated….need help with living expenses.

Hi, my name is Edith. My husband, John, has been battling diabetes since he was 21, he is now 53. He has Congestive Heart Failure, high blood pressure, Peripheral Artery Disease, etc...In November 2018 he developed an ulcer on the bottom of his foot. It became infected and in December he was hospitalized because of Sepsis. He had a heart attack while there and had to have 6 stints. On February 5, 2019, he had to have his left leg amputated above the knee. In March 2018, I had 2 ischemic strokes and am in poor health also. We had been scraping by until he lost his leg but now we can't seem to get our heads above water. Any help would be greatly appreciated. Thank you so much for your time.
