Time To Say, "Move On...?"

Grieving, like everything else in life, cannot last forever, can it? Perhaps, there is no end to the innermost sense of loss, but can a person go on living under the shadow of death? 
I am making the most of the worst situations in my life the only way I know how: to contemplate, vent and prayerfully make a decision ...Can I move passed this? Can you?
