It could very well be just the numbness of depression. Depression is like being empty or comes on because you have been emptied, then you cry out any remaining morsels, then you don't cry anymore. Then you become numb because if you don't, the pain is greater than the resources you have left, because they've been emptied. I think it all comes back eventually. But its a process. Try not to beat yourself just because you are on a temporary empty.
