Puzzle unsolved

I will crawl before I walk
I will think before I talk
I will throw before I balk
I will look before I gawk

I'm lost but yet I'm found
I'm free but yet I'm bound
I'm not here but I'm still around
I'm not dead but I'm in the ground

I'm your enemy but yet your friend
I'm falling down but yet I ascend
I'm your pain but yet I mend
I'm recieved but yet I pend

I'm the truth but yet a lie
I'm happy but yet I cry
I'm wet but yet I'm dry
I'm giving up but yet I try

I'm an answer but yet a question
I'm a secret but yet a confession
I'm gone but yet in possession
I'm a cure but yet an infection

I'm a puzzle without a piece
I'm a prisoner with no release
I'm a home without a lease
I'm oil without the grease

I'm afraid but yet I'm brave
I'm a killer but yet I save
I'm free but yet a slave
I'm strong but yet I cave

I'm sleeping but yet I'm awake
I'm real but yet I'm fake
I'm intact but yet I break
I'm correct but yet a mistake

Contradictions within my mind
I can see but yet I'm blind
I'm in front but yet behind
I'm off track but yet aligned

Words encourage but yet they hate
We have choices but can't change fate
I'm the predator but yet I'm bait
I'm called up but yet I wait
