Cease to exist

Let the river flow
only clean water is good for drinking
black river is for the dark time
am here lying
not knowing from which river am drinking from
less you realize I will be far gone
destiny never defines the ability
but holds the results of facilities
I was gone just before you found me
I no longer belong anywhere
If I had a heart that will give me a better shelter
maybe then or then will I cease to exist.
