Matilda, I think your asking the wrong question. It's not how would you react, but how do you transform distressing thoughts/feelings into those that reflect you've reclaimed your personal power?
Do you have a strategy to do that? How quickly will you recover from this incident? What will you do to get back on track with your DB efforts?
I'm finding "Feel the Fear and Do It Anyway" by Susan Jeffers to be helpful. Albert Ellis also talks about skills in transforming distressing thoughts and emotions into something more constructive.
