Naturally, the more you think about a certain event, the more it affects you. If it is a negative event, you will feel worse. So in cases where thinking about it cannot possibly lead to any new insights or solutions, the only thing to make it feel less bad is to try to move on. How? By looking forward and filling your life with new positive things.

That said, I'd feel terrible if terrible things happened to me and I was just able to move on. There is some pride and romance in experiencing sadness and grief.
