I would say my stutter isn’t dictated by my stress level as I could stutter just as much when I’m completely relaxed as when I’m very stressed. I rather find that it has to do with how important I feel the thing I want to say is. For example, if I want to say something funny in public or maybe add a point to a discussion among friends. If I really want to get it out quick, it usually doesn’t. In situations where I don’t try too much, like if I’m not as ‘passionate’ about something if that makes sense, it usually comes out more fluently. As for the question, I don’t have any other diagnosis whatsoever. I would say I’m pretty introverted though cause I don’t really like parties. I do like to be social but having a stutter obviously complicates that, so I end up wanting to avoid it either way. Hope I helped you and good luck :)
