Despite a pretty severe stutter I was somewhat this guy in college and am keeping it up with some high pressure meetings at work. It's definitely it sucks the first few times but I can guarantee that once you step up and get what you need to out despite blocks it will make your day and fluency so much better. I hated how much I was prevented from speaking in high school and through a handful of events created a mentality that reinforces always speaking up when 9 have seething to share. You all can do it!! It takes practice and the right mindset. Happy to discuss further if anyone is interested.
