Call me and I won't pick up.

I'm not mad, but sad.

If you don't want me.. I won't give you the chance to leave me.
I won't be there to listen to what ever you're going to tell me.
I'm a runner.
I run.

It's self preservation.
I won't know how to pick myself up when I fall. Not immediately anyway.
So pardon me for building the wall around me.

I'm not mad, but sad.
And I'm trying so hard not to let that pull me down.
So believe that I'm mad, not sad.
