"Anyone have advice on how to deal w/ constant attacking emails."
Just don't respond. She's angry.
'I try to be understanding and validate,"
Don't.
" but when she makes a threat or try to say how things are going to be, I can't help myself."
Yes you can. You just choose not to.
" I know the answer, just don't respond if I can't do so in a way that will help."
From her messages, you can get an idea as to what she's upset about and work on those things. The fact that she is actually angry is a good thing. It's when she has a "don't care" attitude that's bad.
