Seems like just yesterday
You were a part of me
I used to stand so tall
I used to be so strong
Your arms around me tight
Everything, it felt so right
Unbreakable, like nothin' could go wrong

I told you everything
Opened up and let you in
You made me feel alright
For once in my life
Now all that's left of me
Is what I pretend to be
So together, but so broken up inside
