The sum of all

On a destination far away
Debating to follow or go astray
In the end a high price to pay
For just a re-lived day

I know, I'm unworthy at best
While carrying this burden on my chest
Taking no time to rest
Concluding I failed the test

Every night I'm afraid to go to sleep
Reminded of a promise I have to keep
Walking on, the path so steep
It's just my conscious that's so deep

Every day I'm feeling left alone
My depression sets the tone
I'm cold to the bone
My vains turning to stone

I'm just as thee
Choice between blind or to see
I envy a life so free
Unfinished, instead of me

Left with experience to rate
But salvation comes too late
I except it in my human state
To exit at the next gate
