Don't know if anyone has this but when I am talking sometimes I become unable to follow up the rest of my sentences because I forget what I wanted to say so in order to avoid the weird silence of trying to remember the rest I just make up something related and it all comes out weird making me feel like an idiot, sometimes I change the subject abruptly which throws people off. It's not that I am not paying attention to what I want to say because I tend to analyze my thoughts very well, sometimes I feel like I need to repeat things in my head almost to the point of memorizing whole sentences out of fear of losing focus. Sometimes my conversations don't feel natural or fluid. Anxiety worsens this but even when I am comfortable it happens, it is really bothersome. I am not sure if this would labeled as a speech disorder.
