Thank you to all of you who have posted supportive messages.
I'm not in immediate family danger, though there has been an interesting development. Daughter and I had a brief exchange and I said I thought her reply was cruel, it seemed to be mocking my mental health. She told me what she said was a joke and id just taken it the wrong way.
As I usually do, to avoid confrontation, I left it and kept pretty much to my living room. I was accused, in a cruel twist of fate, of being a bully,because I was being quiet,thereby bullying them. I was told I was disgraceful to bully a 50 year old woman ( my daughter) and I was asked to imagine how bad they felt watching me getting more and more frail.
To those who suggest I somehow get them to leave, well, it really doesn't matter which way it goes. I doubt they can pay the utility bills that i now pay (the house was mortgage free when I signed it over to mydaughter) or that I could manage on my own in this large house.
Im now thinking about looking into some form of assisted living. It won't solve the problems my daughter and her partner have about paying the bills, but after today, I'm no longer thinking that their problems are ones I have to solve
Again, thanks for the sympathetic responses
