This is such a sad write and something I can relate to as I've had to do the same thing myself unfortunately. I think, unless you have experienced having to pack someone's life and memories away you don't fully understand the emotional strain of it all. You have done a very good job here Mina...sorry for your loss.
This seems like a sad goodbye, the reflection of longing and loss of a parent filters through the poem real well. What makes it intimate with the reader is the insertion of specific moments such as the piling of clothes and the speaker's remembrance of filling in the parent's shoes as if she was a little girl again. But the sadness rushes in when the clad and white motionless part is introduced. Such sadness. And the end explains that there were previous heartaches that could be cured, but now couldn't, because the person has passed and the heartache just rides the wind endlessly, like an echoing voice.
