No one has yet offered any changes/revisions to the lyric, so I'll be the first. I'll preface my suggestions with the fact that any person reading a lyric for the first time doesn't know the intent of the writer and revising someone's lyric can often change the intended meaning. That's not what I want to do, so feel free to ignore any changes I made. Again, these are just suggestions. My changes are in red font.
V1
I´m just a shadow of the child I used to be
All beauty insidehas been broken by years
Everyday there was something new to see and learn
As I grew older all ignorance was burnt
(Note: I replaced the work "unknowledge" with ignorance because unknowledge is not a common word. 
V2
I used to live in my free world without any cares
Of the god called money that rules everywhere
I´ve never really thought that my soul could bleed
That I would come face to face with all lies and greed
PreChorus:
When did it happen
Who is to blame
The change shattered
All my life and broke my game
Chorus:
I don´t wanna be
I don´t wanna be an adult because now
I don´t wanna see
I don´t wanna see the world go down
V3
Indifference and selfishness I had to fight
"Obey!“ "Work!“ "Pay!“ "Die!“ is life with we all satisfied
I'm not sure of your intention in verse 3, so I didn't make any revisions. If I were writing a melody for the lyric I might make other changes to fit the meter of the song. I would like to hear the melody if you have one written.
