Not worth my everythinq (please tell me what you think)

I used to write
I dont know what happen
I used to sing
Way back when

Im so confused
Why am I not deep

You stole my heart
I want it back

Im a little string puppet
And youre my master
You took every joy I knew
And now im puzzled

I know this isnt the real me
But I cant remember what I was like
Before I lost my sanity
And it was all for you
But not worth

My everything
