I Walk Home the Same Way Every Night

How much time do i have left?
Everyday is like a bullet in the head
The pain of seeing what i've become
Is more than i can stand
Blink an eye, the years go by
And things change so fucking fast
Nobody told me that growing up
Would mean growing apart
You make friends, you lose friends
You find love, your heart breaks
You look back, and break down
So many questions im not finding any answers
