I think you just need to take some time and breath before you answer questions that make you uncomfortable. For example, when someone asked you questions about why the turkey was still pink, maybe you simply say..."Good question...hold on a sec, I have to wash my hands." Then go into the bathroom, run some cool water over your hands and take a breath. Calm down and go back to the question when you're less flustered. Remember, everyone has something to say...maybe its the people around you who have the issue. Don't blame yourself if you just need a bit more time to respond to stuff...last time I checked, the art of conversation didn't include a stop watch. :-)
