How can I get my mental mother help without money?

Parents divorced for over 45 years; Dad remarried; Mother stayed single for over 45 years. She is 81. Daughters live in California; Mother moved 18 years ago to Nevada, was working, up until 2 years ago--laid off, on unemployment and social security retirement, until approx,. July 2010; money ran out. Since March 2010, she has been calling (I provided her with a cell phone and pay for it since 2008) and telling me she can no longer afford rent, her car, her bills, she is not eating, etc.--she will live out of her car, or be homeless, etc.

Stupid me, since that time, I have sent her money that I do not have and have been struggling myself, along with everyone in my household (who is on unemployment, desperatley seeking work, but nothing so far), trying to keep a roof over my head and having to file for BK, as well...I sent her what I could over those months. I have spent time looking into what resources (ie., food stamps, etc.) that she could apply for---after all of my suggestions while she was still living in Nevada, and she always had excuses for not driving to the Administration offices, etc.; then continuously telling me she had been knocked down and robbed; someone attempted to break into her apartment; and that finally, she had given notice that she was moving, my friends and I went to Nevada and moved her (after giving her 4 options to keep a roof on her head; two of them staing in Nevada), she opted to move back to California.

Since that time, she has falsely accused everyone, including my father who she divorced 45 years ago and hasnt seen her probably about that long ago, of many different things; my friends and I are not sure what is truth or fiction; she has always had some type of "mental issue" from 45 years ago. I thought I had taken the right measure, believing that she would be better off in California---but now I find out differently She only calls when she is out of money and bills have to be paid...and neither my sister, my friends where she is staying, nor myself, can afford to give her money. That is the only time she calls. I have put up with her calling me horrible names and bringing up childhood issues that I wanted to forget and move on with my life, which I did. This is horrible and now none of us know what to do with her, or who to contact.

I was unable to constantly go up to Nevada to assist her; I cannot afford to be out of work myself or my friend and I will be homeless. She cannot live in our apartment (luckily we have stairs and I am under lease--phew!). She has had violent tendencies and both my sister and I are afraid of what she could or might do to either one of us. She told me she was planning on driving herself back to Nevda. Both my sister, friends and myself said fine, go--you have the keys to your car.

Today, she called and left me a message that she the apartment complex where she was living turned her over to collection (obviously she did not give appropriate notice, thereby lying to me and my friends--she said she had to be out by December 3); and that the car was going to be picked up; and that she was broke. My payday was yesterday, and I am broke due to my bills--and in hopes I dont get laid off because of this added stress and the way the economy is going. I already laid out $750+ for her car, $600 for moving her, and my friends have put her up for at least a month.

I thought and my friends thought we were doing the right thing; but I realize that this woman could not be my Mother...it is very sad to say that, but she plays people and cons them. I am not sure the last time she took a bath or shower. She asks my friends at the house she is staying to drive her here and there, then turns on them saying she has no gas---yet she hasnt driven since we drove her down here, and none of us would feel comfortable with her driving us anywhere. She appears to be coherent; supposedly her goal as she had told us at the time of prior to moving her, that she wanted to get a job part time, and keep a roof over her head (which my friends have provided), but as to a job part time--she has not looked; she told me she wanted to collect disability! (Huh??)....

Can anyone give me numbers to call or someone to call to get her help----I am at a loss as to what measures or who to call to assist, and I am sure I am not alone with these issues. Thank you.
