Dumb question: do you have a key on your keyboard that disables the microphone? I don’t have my laptop in front of me, but I know there’s a key that disables the trackpad and another that disables the camera. I realized that I’d accidentally hit those by going through something similar to this.
Good luck.
I meditate. Very occasionally, I still am not ready to sleep, but it still helps me to do that.
I listen to a podcast, if nothing else works.
Mostly, I don’t worry about not sleeping. It took me years to feel OK with not sleeping, but here I am.
Peace.
