Time is a tumbler, our feelings the rocks within.
Feelings begin as jagged, cutting, things. Time smooths and polishes the the edges, highlights unseen aspects. Time gives us perspective and distance.
No wound is ever fully healed. There remain scars and imperfections small pieces of us that never return to 'normal' again.
Time is distance. How many miles the train will travel from the station. Distance grants perspective and removes immediacy.
Time can't heal though. Time doesn't exist. We made it up in order to make more sense of our universe.
There is only now.
