I may be a little late to the party on this, but my current new favorite jam is "What Doesn't Kill You (Stronger)" by Kelly Clarkson. Talk about a perfect anthem for me right now. In case you aren't familiar with it, the chorus is:

"What doesn't kill you makes you stronger,
Stand a little taller,
Doesn't mean I'm lonely when I'm alone.

What doesn't kill you makes a fighter,
Footsteps even lighter,
Doesn't mean I'm over 'cause you're gone."

I listened to it like 8 times in a row today. Makes me feel all pumped up and powerful. What husband? Ha!
