I need some help with nervousness

I need some help with nervousness My stutter has gotten really bad over this pandemic. I’m used to not being able to talk bc I’ve had it all my life so it rlly doesn’t bother me sometimes, but like now I can’t even say my own name or say here for online classes anymore which is so stressful because I have to do that for some of them and it takes like 10 seconds for me to do it and then I get nervous. And in person I’m having trouble with the mask and talking and I’m trying not to speak now which is very hard in some of my classes. If anyone has any tips on how to help with this I’d rlly appreciate and thanks for reading the post :)
