My recommendation... higher a vocal coach... and have them stand one foot away from your dominant ear and yell at the top of their lungs for one hour. Six sessions of that and you might be ready...
IMO, IF she calls, answer. Say nothing, if possible. If opportunity arises and your emotions are in check, validate as appropriate. Then when she's mostly done and starts asking real questions, excuse yourself and tell her that you may be available to talk about it in a week, but if she has any questions, she could email them to you...
