I was talking out-loud to myself by physically making sounds out my mouth. I don’t do an inner-monologue either, to me it feels like I’m ’cheating’. I’d rather not even formate a sentence at all. When you’re by yourself, DON’T even think of speaking. Just close your mouth. This was a VERY, VERY bad habit of mine. I spoke out loud so many times to myself, and I fucked up and blocked in certain words. Then, my day would get ruined and my ego would get hurt. I shut my mouth for a week and didn’t speak to myself or said my thoughts out loud, my anxiety dropped significantly and my speech improved like crazy. It was unbelievable how this habit messed me up.
