Letra da Música: Left Behind - Questions

Looking back I realize
I used to be a fool
Left behind so many times
I never understood
Why people lie
Don't face their own mistakes
I'm just tryng to survive and
No one seems to care

Now I see I was blind
My enemies, they're so easy to find

I changed my way completaly
I've got nothing to explain
I've turned mu back to this crap
Refuse to play this game
I left behind all the lies
The useless fake smiles
Some doors will close now
But I don't really care
