Verse 1

I'm way too busy to be lonely-

Lies I tell the world and myself.

Thing is, I realize it only

When I hear the buzz of my cell,

Verse 2

And it's not you on the other end.

Suddenly I start missing you.

I type out a text, but can't press send,

And I guess what they say is true.

Chorus

You don't know what loneliness feels like

Till you're alone in your room at night

And your friend talks about her love life,

You can't talk to him though he's online.

That's what loneliness feels like.

That's what loneliness feels like.

Verse 3

Work can occupy my mind, not heart.

I think of you each time I pause.

In those few seconds, I fall apart.

Don't know how to deal with the loss.

Chorus

You don't know what loneliness feels like

Till you're alone in your room at night

And your friend talks about her love life,

You can't talk to him though he's online.

You don't know what loneliness feels like

Till you start missing the little fights,

That spark in his eyes that shined so bright,

And you have to pretend like you're fine.

That's what loneliness feels like.

That's what loneliness feels like.

Bridge

Like a blanket of cold air,

Wrapped all around me.

And I act like I don't care,

But wish you could see

This is what loneliness feels like, baby.

Chorus

You don't know what loneliness feels like

Till you're alone in your room at night

And your friend talks about her love life,

You can't talk to him though he's online.

You don't know what loneliness feels like

Till you start missing the little fights,

That spark in his eyes that shined so bright,

And you have to pretend like you're fine.

That's what loneliness feels like.

That's what loneliness feels like.
