I did not send your letter

I wrote you a letter
things I want to say to you
thoughts I cannot voice
except on blank white sheets
safe here where you can't see
so many things you never knew
but wish I could bring myself
to say to you face-to-face
I wrote them in a letter
one I knew I would not send
but I cannot bear to throw it out
I wrote you a letter
because you never knew
how thoughts of you when I'm here
help to pull me through
I run your words through my head
wonder how many of them you meant
and if you ever realized
how much they meant to me
I told you in a letter
how much I think of you
folded, addressed, and stamped
so you would know I care
But I did not send your letter
