You will get absolutely nowhere by telling her how she is so wrong, crazy and delusional. You can see that by the response she gave.
2) Don't try to get others on side to bolster what you think she had done to you. If she is attacked from all sides, she will dig in even deeper, as she says, you can't understand how she feels or what brought her to this.
3) Whatever she does is just fine, as far as your reaction to her is concerned. I think you need to backtrack and tell her that you have carefully considered what she has said and you can now see how you have been insensitive and uncaring. Vow that anything she does or says now is just fine with you and you will support. Agree with ANYTHING she says, no matter how it might stick in your throat. Back off a bit and give her time to think.
