These Walls

I came to learn an instrument,
Started with torment,
My anxieties got the better of me,
And I put walls up all around me.
 
You finally got me to not be so shy,
How the time did fly...
I got to know you a bit,
Great teacher, helped me come out of my shell a bit.
 
New teacher comes along,
Out of my entire binder, knows only one song!
Knows not what the fuck he is doing,
Makes me start, and knows no notes to any but one song,
Can't correct me when I'm wrong.
 
I wish I could wring his scrawny little neck!
But to prison I won't make the trek.
He looks like Ser Pelo (which makes it worse),
He is stupid and at teaching, so much worse!
 
Came to practice mandolin,
Couldn't start, today, anxiety did win.
I'm so sorry,
As my eyes fill with tears, blurry...
 
Please forgive me for giving in, and building these walls....
