I love that book! That’s where I got some of these ideas from. There’s also an extract from John Harrison’s work that explains this well: “You have a divided intention -- speak/don’t speak. But because you have learned to prevent yourself from experiencing painful emotions, you close up and hold back. You push the fear (embarrassment, discomfort, etc.) out of your conscious awareness. ‍ Thus, the block seems outside of your control, because you’re only aware of half the conflict. You know you want to speak, but you are not aware of the simultaneous reluctance to speak because of the underlying fear and pain. You hold yourself back without being aware you’re doing so. That is why speech blocks seem to happen to you.” Also I moved around plenty internationally growing up so I know what you mean about how hard it is. Moving to the US and going to a public school without speaking a word of English at the age of 10 was scary as hell. Sitting in a class day after day and not understanding a word..
