She says:
"My whole life, I was in and out of school," Momsen continues. "I didn't have friends. I was working constantly and I didn't have a real life."
Well, if you value a real life so much, give up this ridiculous charade of pretending to be a badass and go off to college or something like that. Clearly, she loves the spotlight. All her behaviour is simply a way to get attention.
This outburst is just a way for her to play up how 'damaged' and 'bad' she is while she dresses up as a myopic and misinformed version of what she thinks a rock star is. In reality, she is about as rock'n'roll as boiled cabbage.
