What is the meaning behind these lyrics?

I'm scared to death

Of myself

I can't feel anything

I can't feel anything

I have become the pain

I have become my own demons

I'm tired of being a punk

Yeah, like I ever was

I'm tired of being myself

Yeah, like I ever am

[ Lyrics from: http://www.lyricsfreak.com/r/rabbit+junk%E2%80%A6 ]

Like a quarter dug out of a homeless man's pocket

Like a finger torn out from the socket

I tried it and I knock it

I'm just mad, 'cause nobody wants to steal my soul

I'm tired of being made up

Yeah, like I ever am

I'm tired of being tied down

Yeah, like I ever was

Turn the radio on

To the techno station

Keep it a few points off, so it sounds all ruff

Then it matches my head

All static with the meters in the red

I'm feeling half dead

Feel the demons rise

Let the mercury rise

I can't close my eyes
