I understand why you're lookin' for tears in my eyes
Trust me they were there, but now the well has run dry
I was in so deep, but couldn’t get out
I sat on feelings, that I buried deep down
I knew there'd come a day when are paths would cross
And I'm glad it's today, 'cause now I am strong

Chorus
I'm happy, and I can thank myself
If it were up to you, I'd be in my bed crying
But I'm happy, and I know that makes you sad
After all the things you put me through
I'm finally getting over you
I'm happy, I'm happy
[ Lyrics from: http://www.lyricsfreak.com/h/hilary+duff/happy_20405463.html ]
There's a reason why we met
I'm glad that we did, yeah yeah
But when we broke up, I got back a part of me, I really missed
Not saying that you brought me down all the time
There were moments I lived with without light on my side

Chorus
I'm happy, and I can thank myself
If it were up to you, I'd be in my bed crying
But I'm happy, and I know that makes you mad
After all the things you put me through
I'm finally getting over you

All the bitterness has passed
And I only wish you, someone who can do what I can't

Chorus
I'm happy, and I can thank myself
If it were up to you, I'd be in my bed crying
But I'm happy, and I know that makes you mad
After all the things you put me through
I'm finally getting over you

Chorus
I'm happy, and I can thank myself
If it were up to you, I'd be in my bed crying
But I'm happy, and I know that makes you sad
After all the things you put me through
I'm finally getting over you
