Maybe try listening to Demi Lovato's song Give your Heart a Break-- to me it's a catchy song.

Some words/'phrases' that hopefully might help.

Heartbroken

The history of us

I once loved you, but all you did was break my heart

Tearing us apart, broken heart

Maybe try thinking of what the person did in order to break your heart. If you've had a relationship with someone and they just broke up with you, try thinking of what could've went wrong especially if you loved that person when they may or may not have possibly loved you back.
