Only talk to her like this if you are detached enough to do it. Rehearse it in your "voice." Coach yourself on the triggers and how to deal with them.
Tell her "I have been thinking about what you said and this is what I have decided." You have a choice in how you handle it.
No expectations, no fears (you are already dead) and be a leader. You can handle it
Cheers
