do you know this song?

Question

All I remember is one line repeatedly going "what do I do?" and in the video to that song they make a joke about the lead singer in the band sleeping in a closet which at the end show the lead singer closing himself in his closet. Somewhere in the video they have a ex girlfriend of someone in the band saying she helped write the song and gaurds pull her away or something like that. It would be great help if you could tell me whose the band and what's the song.
