But too much pain can cause lack of feeling. Something about having your heart grow double the size and then implode in on itself, resulting in a black hole from which no emotion could escape.

To be honest, I was speaking of a recent physical ordeal I went through. 

Though, I do not find this to be true on an emotional level. For myself, at least. I have dealt with "shutting down" my emotions to survive in the past, but you don't really become numb at all. You just exist in a continual state of denial.
