Hi! Trust me you are not alone…I actually have the same problem except I just have a higher pitch voice. I’m usually a very cheerful, upbeat person but everytime I have conversations with people I noticed that they yawn, even when I begin to speak, and it makes me feel like I’m uninteresting and boring them. At first I thought it was all in my head but I began to notice it’s literally everyone that yawns when I speak to them…i do struggle with anxiety a lot and read some of the comments on here of how that could be a factor so that’s interesting. Anyways, I stumbled upon this while trying to find out why I make people yawn too. Well, I hope you’re doing well and can figure it out and if you do, let me know bc im still struggling with this problem!
