You are getting fantastic advice from everyone else that has posted--I would just add that when I am feeling vulnerable, I react the same way you did to the rudeness and would have done the exact same thing. I know it's not the right way to handle it, but I just want you to know, next time those tears well up in response to someone's rude attitude know that I'm sending hugs your way and telling you to stay strong and don't let them bring you down AND more importantly, don't let them ruin the meeting you are there for!
