A Deathbed Thank you Letter

Potential threat
Walk the path of death
It's what I've chosen
This life is all I have
There's a pain in my chest
Must remain focused
Stand tall again
Every day has an end

All I have, All I Love, All I gave, Was for What?

Who'll be the last
Listen to these words
Will it be, memories
My possessions, will be passed
To the future, from the past

All I have, All I Love, All I gave, Was for What?

What is this?
What am I?
Why is this my life?

I'm leaving them all; This deathbed thank you letter
