When I first started dealing with childhood abuse I couldn't deal with my mom. She was always kind of dependent anyway, so I didn't think she would be the best support. I think this was one of the healthiest things I ever did for myself. I say that because instead of getting all bogged down in her issues and her views of my experience I found healthy people to guide and support me. Sometimes it is hard to work through the maze of childhood and young adult parental relationships and find a way to be together that is healthy. We had some good times and she even lived with me for a few years. In the end the issue of taking care of mom never came up as she died when she was 60. This is NOT a cautionary tale for your daughter. She has to take care of herself no matter what. Seek out help on your own, figure out what you can't do on your own and find out what agencies or organizations can help. My mom and grandmother did that since none of us could be close due to work. Finding support groups helps too.
In the end my mom gave me loving space and that gave me more reason to resume contact when I was ready.
