I will have to leave

Taken from this world without warning
You left me here mourning
Six years have come and gone
Yet I still feel all alone
The pain now dim, but always here
An ever-present reminder of my fear
You believed in me when I didn't believe in myself
Always said best to be yourself
That I was perfect as I was
and shouldn't give a damn
what others say or think
for they will be gone with just one blink
but now it is you who has gone so fast
your life just could not last
but your words are with me everyday
you taught me to never put off what I can do today
for tomorrow is not promised to me
As your death has made me see
It opened my eyes to the truth I don’t want to believe
That one day it is I who will have to leave
