85 yo mom was hallucinating and is delusional. Any advice?

Checked for UTI and blood sugar levels, blood sugar high but no UTI. Due to the fact that she had wandered off thinking there were people coming through the tv and were in her apartment, I requested she be admitted to the psych ward. So far all I've been told is that she can probably no longer live alone. I'm at my wits end. She usually does not take her meds when she's around me even when I try to encourage her to do so. She usually tells me off. I'm afraid they will release her tomorrow because she's been so "sweet, and such a joy". I have three kids and a husband at home and I don't want her to live with us. She keeps telling all the staff that she doesn't want to live alone. I don't think she will take whatever meds they have her on once she gets released and we'll be right back where we started. I guess this is just a rant. I think assisted living would be best, but there doesn't seem to be many that take Medicaid. I was trying to work with someone to help me get her qualified, but got interrupted by this last crisis. Will a social worker try to mediate between my mom and me and try to persuade me (in front of my mother) that family is the best place for her? I wouldn't want my mother to hear me say I don't want her to live with us.
