Not saying that big girls shouldn't cry though.. because I for one cries a lot *LOL*
The singer, Fergie wrote it when she was trying to break out of the drugs and parties scene she was trapped in. She was telling herself to be a big girl and move on from things that was holding her life down. That would mean going to the rehab and break up the relationship she had with her boyfriend at the time, because he was heavily associated with drugs. It hurts, but she gotta still do it. And she became a succesful singer after that! Sounds so fairytale-like doesn't it?
This reminds us of our life sometimes. It really sucks to have to move on from things that we had found comfort and happiness in. We often hesitate from moving on even though we know that it's for the best. Cry as many litres as you like but move forward and keep a positive eye on it. I'm sure that the best is yet to come! :D
