Since you are potentially speaking of my post, I will explain what I was talking about and hopefully ease your mind a bit. I experience pressured speech. At my worst, I would converse in my head and it would just burst out of my mouth...and I couldn't control it or shut up and didn't always even notice it. My oldest daughter and sometimes even my husband picked up on it and knew it was abnormal and would call me on it. My laughter was a nervous laughter. It was usually caused by me recalling something I had done embarrassingly (which is pretty much everything when I'm manic) and then bursting into laughter, again my daughter picking up on it. She knew these things were odd. I did my best to explain things and it wasn't incredibly hard since she was still so young.
