Agent Sparks - Mr. Insecurity

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 and say

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!
I'm a critic and 100 years old
A product of dysfunction,
"Oh pity," I'm told
I'm never good enough to fill up my bowl
To stand up and say

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
