Let the breakdown commence...again

Well, My mother was home for 5 days - got sick - went to the hospital for 3 days, and is now back in the nursing home.
The 5 days were a nightmare - I can't do that. I can't live like that. 
She will have to go into a facility for the rest of her life, however long that is, and she will not be happy. 
I'm living in her house, and once she goes on Medicaid - which will be within a month of the Medicare benefits running out - Medicaid will start racking up the bills owed to them and, once she passes, put a lien on her estate. In the meantime, I keep hearing, from a variety of people that do not know any better, that they are going to take her house or put a lien on her house, etc., and I live there, have no way to move and no place to move to.
Meanwhile, my daughter has asked me to have her committed to the mental institution for a week in order to keep her from killing herself, because she's in too deep with the social crap and academic crap at school and she cannot handle it. She doesn't want to go and face the rumors that are being spread about her, and has no friends among the adults at the school any more, because the investigation into an incident she was involved in came up with no proof so they blamed it on her.
I don't know how to manage all of this crap - My mother, the girl, and this house - it is all too much for me. If it was just the girl, I could cope, but taking on my mother and/or her house is way over the limit - and neither of my brothers are any help there.
So, here I am all alone with way over the limit to deal with and no body to help me with it.
