I've found that when I go thru those almost unbearable painful times, I come out with a different level of acceptance.
I think I have begun to notice this as well. As much as it hurts and is evolving away from our long term goal of R the toughest times cause us to grow the most.
I feel for every one of us suffering out here and hope one way or another we can all find the peace and happiness we desire and deserve.
