I know exactly how you feel. I’m also in Cybersecurity too, as an Architect. Chasing perfect fluency is a battle you will never win as a stutterer. The sooner you accept that, the better your state of mind will be going forward in your personal life and career too. You’re doing really well at 85-90% fluency. Why isn’t that good enough? I totally get the feelings of anxiety and frustration of anticipating blocks etc… I spend most of my days on video conference meetings, so I get where you’re coming from. You can still get your ideas and points across right? You’re high functioning in your job? If so, be proud of yourself and don’t sweat the little slip ups here and there. No one is perfect, and if anyone judges you, fk them! 👍🏼
