Bills, meds, and utilities are more then monthly SSI. Mom has dementia, diabetes, stroke and more. I'm the only caregiver. What do I do?

3 years ago my mom had a stroke. Then a heart attack, and progressing dementia. She's had a lifetime of uncontrolled diabetes, and high blood pressure. Due to her own bad control. I was appointed by siblings to be the one to live with her and take care of her with the help of all family members. I had just lost my job of 10 yrs. Well the help lasted a week. 1 week. My mother was a out spoken, rude, very pretty, thought she was better then everyone else kind of person. Growing up with her was hell.

Now 3 years later. Her money is her monthly SSI. And the bills, credit cards, meds. Medical bills, utilities, house payment, insurance 's, etc. Are drowning us. I'm not paid for 24/7 care. No unemployment. I am burned out, resentful, and don't know where to turn. Medicaid denies her. No money for hired help. What do I do?
