I don't feel like it's unhealthy. I'm not unhappy and I can still connect with others. But I think every stutterer can relate to an inner anxiety that they won't be able to fulfill a duty (social or otherwise) because they can't be confident in their speech. Like having those dreams (which I think is pretty common, even for PWDS) where you go to scream but nothing comes out. Every now and then I just like hearing myself be ungodly loud :D
