Idk if it’s called physical symptoms or not but as I could rmb many months, I had tough times splitting those words out and I started to make a weird face like right eye closed and nose went nose a bit. I noticed ppl I was talking too also be making weird faces like sth in their heads prolly be like “what’s going on with this dude”. And the fact, I’m a typa person who tries to this the sentence I wanna say even I stutter so bad. Since I have used to breathing method, I reduced making that kinda face again whenever I’m finding words or trying to say those words out.
