Hey! I think it all boils down to confidence when it comes to your case, cause you're scared of the judgement how these people are going to view you when you're going to stutter, I have th same issue and I'm currently working on it. Also I've noticed that when you're used to a particular person or feel comfortable enough around them the anxiety and stress reduces and so the stuttering. Keep pushing we have this. We should have a mindset of confidence for that you should trust your skills and know you can do it.
