This is such a sad poem. I am terribly sorry for your loss. I love the structure it contributes to the flow of the poem and the flow of the poem somehow enhances the sadness of the subject matter. It is a real tear-jerker.

The internal conflict of both wishing not to remember the pain and having no escape from the grief because the memory is a burned-in scar on your heart. Everybody has them and I think this poem has all the parts needed to resonate with those painful moments to allow people into your headspace at the moment it describes.
