I am experiencing this problem. My fluency has steadily gotten worse because of the lockdown. Before this started, I was mostly fluent and very comfortable with my speech. I've been working on my fluency all of my life. The social isolation caused by working from home and seeing friends & family less is really taking it's toll on me. Video and phone calls have always been a little bit less fluent then in person communication for me, being forced to only communicate that way for work has been really hard. Masking has added to my anxiety and made it worse as well. Before, when I stuttered, at least people could see I was blocking. Now with the mask on people just can't tell. I'm not sure what to do about this either. I've been taking every chance to go out and socialize with people in person, prioritizing my mental health and fluency concerns. I've been thinking about relocating to a city that isn't as restrictive with covid lockdowns or finding a employer that has staff on site. I'm really afraid it's going to take me an extended period of time to bounce back from this.
