The chords are better off being played as barre chords. It sounds better to me that way

Intro: A

A                C#m          
Sometimes I get my head in a dilly
D                Bm
Feeling so lost ticking you off
A

C#m
Said, I'm that kinda feeling
D
That kind of soft
Bm
That kind of silly
A
But when I'm in doubt
C#m
I open my mouth
D
And words come out,
Bm
Words come out like

F#m                           D

I caught them barking at the moon
E
Better be soon

A
High in the sky
C#m
The song that I'm singing
D
A sweet little lie
Bm
A cry wolf cry
A
Rather have you lie
C#m
So that's why I'm bringing
D
Some tricks up my sleeve

For noticing me

I can't help

I can't help myself
