Saying "Have the right mindset", or "believe that you can get well", otherwise the program won't work, is just another way of saying "you are never allowed to question or criticise". She, like many other psychoquackers, has set up her program/method so that she gets to be 100% right all the time and immunity from criticism is built into the framework.
Is that something that someone who was genuinely interested in helping would do, deluded or otherwise? Smacks more of egomania to me. Even if she's deluded, she should be banned from taking money from the sick in return for a useless program that they are not allowed to have an opinion on or it won't work.
