Let's face it if anyone else had tried to tell Jade what the Psychologist obviously was able to tell her, she would have thrown a hissy fit and torn them to shreads. The fact that the Psychologist was in a position of authority and also part of the BB team gave Jade no choice but to listen, and was the only way that her bad behaviour, that had actually got very much worse lately, could be pointed out to her in no uncertain terms . By the Psychologist telling her straight, facts about what she has been seen doing, was I think enough for Jade to finally wake up and realize just how bad things had got, especially under the influence of alcohol which was not doing her any favours and was actually quite damaging not only to herslf but to some of the other housemates who were getting the brunt of it too.
I am not sure if her wish to change and improve will last, but any small improvement is better than none, only time will tell if she has really taken anything that was said on board...I don't hold out much hope!
