One of my most affective intrusive thoughts

It’s so simple but it’s so jarring and I cant seem to get it out of my head. ‘Shut the fuck up already’ - It seems so light but I cant express this enough, EVERY TIME I TALK I GET THIS. It’s like a loud frustrated yell and there has been multiple times in public where I’ve had to say ‘Sorry, my brain. Anyways‘ BECAUSE OF THIS THOUGHT ALONE. It definitely stems from my worry of sounding dumb + annoying while speaking, but wow. Thanks brain! Way to make my anxiety lessen.
