I have a mentally disabled mother who is being put out of Emory Hospital and she is still a threat and harm to

She can be a threat and harm to others. She has Huntington's Chorea and she is in her 4th Stage, She is on Medicaid because we don't have enough money to provide for her. About 6 months ago she entered into stage 4(which is the last) and has now completely lost her mind, and cannot be unattended at anytime. She see's people and talks to people and sometimes listens to what they tell her to do. Now Medicaid will not pay for her to stay in the hospital any longer, and they gave us the option of coming to get her, or paying the bill myself. Now I'm 20 and I'm doing this on my own, so I cannot pay for her hospital bill, and I do not have anywhere to put her. She is not eligible for hospice, and nursing homes are refusing to take her due to her age(40) condition, and the fact that she is on medicaid. She lives in GA, but I was just wondering, Can anyone please help me in anyway. or give me any kind of information that can help me even if it's just a Huntington's hotline number. Please Help
