I get it. We've all been there. It's easier to not say anything then stutter. The only way I've managed to deal with it is to just push through it. I just think I'm just going to stutter and people can either deal with it or get fucked. Eventually the act of stuttering doesn't affect my mental state so much which helps me relax which helps me stutter less. I still have shit days though. I know you didn't really ask for advice but just wanted to share.
