So I sometimes do the rosary which is a prayer and meditation cycle, for someone. In 1992 when a friend was dying of cancer and I couldn't just sit with every one else at her bedside, I ran loop after loop around her road. This was my own response and attempt to 'do' something, when nothing could be done. At some gut level, I hoped that running myself into the ground would somehow reach and help her, as silly as that may sound. This obviously isn't your fancy, coach-type, objective running advice, but I hope it gives you food for thought.
Some slumps arrive and depart in their own good time.
