I think that this song means that there was a girl that would feel okay around guys and she wouldn't be nervous around them at all until she finds a guy that she actually likes a bit. She gets nervous and scared because she's never actually been in love so she tries to impress him by acting more girly and tries to hide her true self. But whenever she does try to be herself it just goes all wrong and she embarrasses herself in front of her crush. So she keeps on trying and trying until she can't take it anymore. That's my opinion.
