The numbing, I agree, is quite freaky. It weirded me out when I realized most people don't go through life able to recount difficult events with no emotion. I sympathize because I have some choking stuff in my past, too. Shudder.

For me, the emotion came when I told my counselor about what happened in a truthful, honest way. So instead of being all, "it was no big deal," we talked about it being a Big Deal and a Damaging Event. Seeing it for what it really was helped me face it. I suspect that the more you let yourself think about and process the memory, the more feeling will come back.
