Yea this is the best song of avril. The deepest one. And yes it's about a brokenhearted girl. This is one of my fave songs caz it tells everything about me. A girl who had her heart broken by some guy and it somewhat stopped her world, stopped living her life. And suddenly she realizes that she's had enough, enough share of pain. And that she shouldn't waste another minute of her life over a guy again. There's more to life than just falling in love. Go out, live your life the fullest, and do something you're good at. Be something!
