Write into what has vanished .

"Writing is a window. It opens onto vanished feelings and vanished worlds." ~ Louis Menand

Emotions come and go. We can wrestle them to the ground or acknowledge them and let them fly. Even if they appear to vanish into the horizon, they will return in other colors, shapes and sizes.

Write about your window into feelings that vanished. Where did they go?  Did they return in other forms for reconsideration?  Write into, around and through them.
