英語得意な方訳して欲しいです

It will be the day when it already forgot it
Surely I think that thus I am good
It was a slightly disappointing end it would be good, too
But I cannot get through this day plainly
I will write it down here from such thought
Good-bye for mysterious relations
Good-bye to you who loved it
I walk a way without two people crossing again from today
While having a mysterious pain…
Absolutely find happiness!!
