Who I am Lyrics

There is something with anger, depression and pain
There is something going on, what I can't explain
And everytime, when I am happy and I feel well
Something special happens kick me back to hell

Everytime when I feel fine there is still pain
One sentense couldn't change it, I can't explain
I can't explain what's going on am I just a toy
Who can't thing, the hand on strings, no joy

Many bad experience makes me feel so hard
But I don't wanna give up don't wanna get apart
And I hate the humans, they walk in a convoy
I don't wanna be abuse, I am not your boy

Always thought that I could achieve everything
So I gave what I had to give and got nothing
And all my visions they are dead
Someone had cut it of and stole my (bloody) head

???Who am I???

I'm not your boy
