I've Convinced Everybody But Me lyrics

The guys down at the job all want to know
How things are goin' since I let you go
I laugh and say my heart ain't missed a beat
I've convinced everybody but me

Chorus
I'm all right, I'm okay, that's what I always say
When they ask me how I'm doing without you
I say I'm glad I'm free and if they all believe
I've convinced everybody but me

I'm the life of the party every night
Nobody knows I'm dyin' deep inside
I don't hurt at all as far as they can see
I've convinced everybody but me

(Chorus)

I smile in every mirror
Like I'm such a happy man
But my heart knows what a liar I am
(Chorus)

Yes, I've convinced everybody but me
