Mr. Insecurity lyrics

Please simplify how I'm supposed to do this
I'm all alone in this intervention
I'll poison waterfalls with tree sap
And piss to stand up

I take these vitamins so I can forget
About the pointless thoughts taking precedence
My imagination makes me useless
To stand up

This is only going to break my heart
This is only going to tear me apart
This is only going to break my heart
So come on

I've lost my mind many dozen a times
I had a heart scan and thought I was going to die
Disease and doctors threw me a sign
To stand up
[ Lyrics from: http://www.lyricsmode.com/lyrics/a/agent_sparks/mr_insecurity.html ]
I'm a critic and 100 years old
A product of dysfunction, "Oh pity," I'm told
But I'm never good enough to fill up my bowl
To stand up, yeah

This is only going to break my heart
This is only going to tear me apart
This is only going to break my heart

This is only going to break my heart
This is only going to tear me apart
This is only going to break my heart
So come on

Is it me, the person you can't read?
Is it me who can never fall asleep?
Is it me, Mr. Insecurity?

Can I be a happy human being
Who doesn't think about himself or me
I'm sick of being Mr. Insecurity

This is only going to break my heart
This is only going to tear me apart
This is only going to break my heart

This is only going to break my heart
This is only going to tear me apart
This is only going to break my heart
