He wrote: "The whole purpose of making this film is to give therapy and the tools I've learned in therapy to a wide audience for private use through an entertaining film.
"Through this journey of self-discovery within the film, I have come to the understanding that I have spent nearly 20 years experiencing anxiety attacks, which are exacerbated by media appearances and public-facing events."
