In a weird way, having your worst fear happen is incredibly liberating. The thing you were most terrified of comes to pass...and it's totally fine. Life goes on, gets better. You feel more confident and capable, knowing that reality is almost certainly kinder than your fears. Anything that comes up after that, you know you can handle it and be ok. Everything shifts with that realization. It's almost like we were superstitious before. "Oh, I have to do this, this, and this or some terrible fate will strike me down." So, we stay stuck in our painful fear-based rituals. It's actually good to get knocked out of them and see that we're better off with the "terrible fate" than our own distorted thoughts about preventing it.
Or, it was for me. :-) Maybe you can relate.
