All at once

I fin'lly took a moment

And I'm realizing that

You're not coming back

And it fin'lly hit me

All at once

All at once

I started counting teardrops

And at least a million fell

My eyes began to swell

And all my dreams were shattered

All at once

Ever since I met you

You're the only love I've known

And I can't forget you

Though I must face it all alone

All at once

I'm drifting on a lonely sea

Wishing you'd come back to me

And that's all that matters now

All at once

I'm drifting on a lonely sea

Holding on to memories

And it hurts me more than you know

So much more than it shows

All at once

All at once

I looked around and found that

You were with another love

In someone else's arms

And all my dreams were shattered

All at once

All at once

The smile that used to greet me

Brightened someone else's day

She took your smile away

And left me with just mem'ries

All at once

Ever since I met you

You're the only love I've known

And I can't forget you

Though I must face it all alone

All at once

I'm drifting on a lonely sea

Wishing you'd come back to me

And that's all that matters now

All at once

I'm drifting on a lonely sea

Holding on to memories

And it hurts me more than you know

So much more than it shows

All at once

All at once

I'm drifting on a lonely sea

Wishing you'd come back to me

And it hurts me more than you know

So much more than it shows

All at once

And that's all that matters now

All at once

I'm drifting on a lonely sea

Wishing you'd come back to me

And it hurts me more than you know

All at once
