RJ42,
I think numbness is both good and bad. Good because you don't feel sad. Bad because you don't feel happy. However, I was unable to feel happy without feeling sad. I hope your luck changes; something good might have to happen to you in order to emerge from your numb state. Hang in there and take care of yourself -- I think the future is unpredictable (and I want you to outlast your ex-wife!).
