Lockdown and wearing mask increases my stutter.

Lockdown and wearing mask increases my stutter. Today i went to nearby shop and i forgot wearing mask(i was in a hurry). I noticed something, my stutter decreased a lot and confidence rise a bit. I don't know why it happened maybe because mask hides all our emotions and i can express or talk silently behind the mask. During lockdown, i barely interact with peoples and only talk with my close friends. So obviously i am under confident and mask adds up the problem. Is it me or this thing is happening to anyone else?
