This is a great poem. Many people can relate to. It flows well and is a mix of emotions like anyone's would be when a relationship ends.
Good piece.
I think the first line on the second stanza would read better as 'my confidence says the feelings are temporary'
On the second line of this stanza you write 'and that, they will go away soon, but m not sure' I think you meant to put "I'm" there.

On the third line in the second stanza you wrote 'its been a long sine you left' I think you should have written 'its been a long time since you left'

I so like the contradiction within the piece as it shows the body and minds state of confusion when someone leaves etc.. Well done
