bunny its really hard when you see some genuine emotion of sadness. It makes it all worse, really. Such a pity that it's not possible to connect with someone then, givne what tends to follow :(

Shadows, it must have been a hard decision to go NC but in your shoes the hair would be creeping on the back of my neck with anger - rage- at those documents. Agreed, the priority has to be your children. And, you know ... yourself. She sounds just too subtly poisonous. Claiming loss of grip on reality, my biol. mother did that too - highly ironic in the circumstances. A truly nasty insidious trick.
guggenheim it sounds like she is highly emotionally unstable. I did ring somethign long ago about how parents like that tend to have children with a higher than usual proportion of schizophrenia becuaes they are taught from an early age that their own perceived reality is not to be believed. Their mothers tell them that their reactoins (such as sad if something bad happens, happy if something good happens) are wrong and how they ought to feel. The children loose faith in their own perceptions. So it sounds like you've been pretty strong to keep going with her this long and your feet on your ground and have faith in yourself.
How to deal with it? hmmm. How about trying the old method of keeping neutral? actually tuning out and replying with neutral phrases like airofHope wrote on the last page? "I hear what you're saying" "ah, I suppose that's true" (to any point she makes, while not paying much attention) etc etc. It means giving up any hope of a real genuine person-to-person relationship but that possiblity has long been gone from what you say. I wouldn't suggest such patronizing softsoap in dealing with a more normal person, but with some people you cannot get through.
I think you are feeling upset becuase basically you're being invalidated. You are more of a listening board for her take on things, rather than an actual person who happens to be her daughter. If I'm right about that, then trying to connect with her must be an immensely frustrating and disappointing experience.
you may find it easier to quietly and unobtrusively start contacting her less. Highly mood-swingy people like her are very wearing when you are around them for long at the best of times, never mind when you're the actual daughter.
Hope that helps a bit ...
