You are giving her too much credit for thinking.
She is working on emotions and adrenalin right now. When that is not working then she is in a deep funk. She needs the space to process all of what is going on around her. Most of this has absolutely nothing to do with YOU. It is all about her. LET HER GO to work on these things. It is actually the most humane thing to do. Like coming upon a wounded animal and trying to pet it to give it comfort. It is more likely to snarl at you and bite you if you try this.
