if she is the English 'medium' lady - then she has been proven to be a massive scam ... I won't going details, but she seems to be a truly awful human being who has her team intimidate anyone who tries to come out with the truth about her... you can find quite a few articles about this on the Guardian for example, but also lots of info on Reddit...
when I first saw one of her 'medium' shows online (this was back in 2013), I thought: WOW! But, it was nothing but a good PR ....not my business to tell you what to do, but a friendly advice: save your money. xx
