Oh yeah, absolutely. All the bloody time. Sometimes I have a great joke but I am afraid to deliver it because I know I am going to stutter and everyone has to awkwardly laugh even if they didn't understand it. Sometimes I want to comment during a discussion but I don't because everyone will look at me and I will get nervous and start stuttering. It's kind of sad and I feel really bad about myself for doing so. But what can ya do? No matter how many times I convince myself that this is the wrong thing to do and I am only destroying my self worth, I just can't make myself do it.
