Withdraw, I'm with Anne, don't beat yourself up. My interview sucked, I totally froze up and couldn't think of anything to say. I thought I was ready to relate my story but I did not do so to my own satisfaction. As more time goes by, however, I find I am getting more comfortable talking about it. You didn't fail anyone. Our experiences were all similar but also all unique, there is no "standard" time in which to get over all the fear and guilt and self doubt that these places instilled in us, we all do the best we can.
