Hi Warrior33,
It sounds like she's dysregulated, was she raging at you? There's not much that I can say, it's not a good idea to try to reason with her, I suggest to not JADE, don't justify, attack,defend or explain, she may bait you, I don't recommend arguing with her etc... You could try validation, but don't validate the invalid, you said that she has a valid reason, I don't what to tell you validate if I don't know what it is.
Don't "JADE" (justify, argue, defend, explain)
