Unfortunately, the best thing is going to sound contradictory, but it’s what’s suggested by SLPs who specialize in dysfluency, or are PWS also. Let people know you stutter. Bad blocks happen because you are trying *too hard* to hide it. Start by looking in mirror and doing voluntary repetitions. Build up to calling businesses, and then in person (maybe walk around the mall). Try to incorporate this into regular speech. Make regular eye contact, begin slowly and on a exhale. Here is a link to a nationally recognized organization with many SLPs, and PWS, with a combined dozens of advanced degrees. Please do not drink alcohol, make complex analysis spreadsheets or take advice that’s just “calm down”. Breathing out can be a helpful practice, *but please talk on exhales bc that’s what happens naturally*. https://www.stutteringtreatment.org/blog Tim Mackesey (SLP) has a free podcast that helped me become sustainably very very comfortable speaking in any situation.
