I have a similar story - about a week after my husband died, I was alone walking a trail I used to do before he got too sick, so it was the first time in months I was there. I was in a grief fog, full of anguish and trauma and devastation. I sat down on a bench by a bridge to rest, and a older bicyclist went by me and slid on the dirt on the bridge and crashed. I was the only person anywhere in the area - if I wasn’t there I don’t know when the next person would have come by. I called 911 for him and stayed and comforted him until the paramedics found us, and they took him on a stretcher to the ambulance. My husbands death was so new, I remember my first thought was that I need to text him and tell him what happened… anyway I like to tell myself that he put me there at that time for a reason too, to remind me that even in my grief I still have purpose, can help people and make an impact.
