Hi Distressed2010,
I'm afraid I don't have much as far as advice right now. But I recently found this article and I thought you might relate...

...The only thing is that I think there is a typo in the article. In the corner it says of toxic people that they can be "mean to others, nice to you." I think what they meant was "mean to you and nice to others." Well that is my experience anyway. (This is my mother when she is in one of her moods).
