My mother is homeless and mentally ill. She is now detained on a chapter 51, and was transferred to Mayo clinic in Wisconsin. I'm not sure what to do.

I am her son and looking for advice. She is recently widowed, my step father passed 2 months ago. My mother is 54 and has had 3 strokes, open heart surgery and is epileptic, among many other issues. She is homeless and suicidal. She can barely walk, she cannot live alone but she has no income, no disability. On Sunday night the 21st of January I had a friend take her to the ER . She is now on a chapter 51, and was transferred to Mayo clinic in eau Claire Wisconsin. I'm not sure what to do.
