i can't survive anymore

someone told me,

if you want to forget someone
put all about that person into the box
key that box

throw that key as far as possible

and put that box deep inside your heart

let the box still in your heart
without having to open it again

I have been trying to survive with your attitude
but now i can't survive anymore
I am not as strong as you think
sorry
I had to put all of our memories into that box that I would never go back

if you want me to back i promise, you will never find me to back
