((((zoo)))) I'm sorry this happened, I really am. I know it hurts to feel dismissed so abruptly.
Perhaps what sounded like anger was a hurried, rushed, impatient tone, like she was frazzled by things right at that moment. And she just took your words as permission to move on....I don't know, I hope you can find the answers you need.
I agree with WePow....let yourself feel the hurt and anger, but also do what you need to do to keep hold of your peace!
