I'm sure that you won't want to do this, but personally I would be tempted to go to the local paper and tell them that your daughter, who is responsible for re-housing homeless people is actually evicting her own Mother, making her homeless!! At least it would be revenge of a sort, although, as I said, I doubt due to maternal instincts that you would do it, but it's really what she deserves. I don't know how she can be such a heartless bitch to her own Mum, and that's from someone who has has also suffered severely at the hands of her own daughter over recent years. I have tried so hard to forgive her, thinking that the bond between Mother and child could never be broken, but it has, and she has literally broken my heart. We are only human, and to be hurt so badly by a child that you gave life is beyond evil. Sorry, I know that's harsh, but the way some of our kids treat us as we get older is heartbreaking.
Anyway, whatever you decide to do, I wish you all the very best and please, please, don't give up on life although I'm not surprised that you want to after being treated so abominably.
