Yeah, I have this often when on days that are less functioning. Similarly to being unable to put word down on paper, speech is like the same thing.
Often, Even meeting or greeting people or to express an opinion or whatever the conversation. When speaking, I often either forget the words to say, or that the though gust goes by. It's tough when I could have something great to say, I can't express it in words and often frustrating.
Often mid sentence, speech can just stop to a standstill, or that I need to answer a question. I often noticed speech fluidity of my peers. They often talked much faster, louder, without pause, which made me look like an sensitive nervous shy kid straight through my life.
It's often the thing that has outright prevented me into employment at the interview stage, its not going to happen without the interview stage being skipped completely, despite years of communication training.
