I find this website to be an amazing tool for just this sort of thing.
It is free for one (I think one) belief of your choice. I recommend choosing 'I'm not good enough.' I love to imagine a world in which no one believes they are not good enough.
There's an interactive video that walks you through the process. They have an option to pay for more, and you can schedule sessions with people well versed in the process for money. But money is not necessary. I have done the process by following the book (before the interactive website was available) and had great results.
