C/B is a transition between C and Am, you can skip it but I suggest you try and play with it.
[Verse 1]
Am D
Nine months since I licked you clean
G C C/B
And left with no complaints
Am D
I jump blindly into your arms
G C C/B
I'd never been so brave
Am D
And each day brings a storm
G C C/B
I'm simply not prepared to face
Am D
And I sleep and I dream
G C C/B
Between my grave and your sweet face
[Chorus]
Am C
But I've... been waiting... waiting...
G
Oh I'm waiting...
[Verse 2]
Am D
Mamma blessed me with confidence
G C C/B
I'm distant to embrace
Am D
Well feed me something that's strong enough
G C C/B
To very sorry place
Am D
I'm fucking losing my mind
G C C/B
And I can see it in my face
[Chorus]
Am C
But I've... been waiting... waiting...
G
Oh I'm waiting... waiting...
C
Oh I'm waiting... waiting...
G
Oh I'm waiting... waiting...
C
Oh I'm waiting...
