I read her first autobiography. In it, she did say that she has tried to get normal jobs but because of her infamy and appearance, a lot of places won't touch her. For example, she got a job in a pub, but people kept shouting Eastenders catchphrases at her and wouldn't let her get on with it.
I should add, in her autobiography, she takes full responsibility for her actions. She blames nobody else for her drug abuse etc, despite how young she was when it all started for her.
