Am I the song?

Am I the song 
or just the instrument 
you used
to create the song

why do you make me feel like I'm just the instrument you used and forget about
am I really just the instrument?

my mistake I guess
I misunderstood your affection 
for a connection that was not meant to be 
I misunderstood the time you spent with me 
thinking that was love 
but apparently, what I called love 
was just a time pass for you

looks like I'm just the instrument 
that you used
forgive me for wanting to be the song you created 
I'm just a human 
with desired that'll not be fulfilled 

forgive me 
for wanting to be the song that is loved and appreciated by others
instead of the forgotten and left behind instrument.
