Broken Promises lyrics

I break my promises
And I just broke one to you.
I promised you I'd try harder
And I guess I've messed this one up too.

Now, I'm begging you for another chance.
No, you shouldn't give it to me.
But I swear to heaven this time I'll get things right.
But you ain't gotta believe me.
[ Lyrics from: http://www.lyricsmode.com/lyrics/c/candice_jarrett/broken_promises.html ]
When you pick me up I let you down.
I blow out your candles
And I stand my ground.
The screen of the TV is as black as my coffee.

But my heart is the darkest thing around...
My heart is the darkest thing around.

I break my promises
And I just broke one to you.
I promised you I'd try harder
And I guess I've messed this one up too.

Now, I'm begging you for another chance.
I know, you shouldn't give it to me.
But I swear to heaven this time I'll get things right.
But you ain't gotta believe.
You ain't gotta believe me.
