I remember when
I used to walk an easy life
Then you stepped in
Stepped me right out of my mind
Now there's is a fire runnin' through my veins
A hammer poundin' in my brain
There are some things
That I just can't explain
So, girl, don't ask
I can't relax
I can't relax
I never knew my heart could beat this fast
(I can't)
I can't relax
Can't concentrate
You shadow everything I see
I lie awake
This anxiousness won't let me be
'Cause there's an instinct
That I just can't tame
And this feelin' drives me half insane
When dreams possess me
To call out your name
My pulse reacts
I can't relax
I can't relax
I never knew my heart could beat this fast
(I can't)
I can't relax
I can't explain it
I remember when
I was happy sleepin' on my own
Took over then
Now I can't face one more night alone
Now there's a fire runnin' through my veins
And a hammer poundin' in my brain
I can't decide
If it's pleasure or pain
So, girl, don't ask
I can't relax
I can't relax
I never knew my heart could beat this fast
(I can't)
I can't relax
I can't, can't relax
(I can't)
I can't relax
I never knew my heart could beat this fast
(I can't)
I never knew my heart could beat this fast
Relax
I can't, can't relax
(I can't)
I never, I never, I never knew my heart...
