help ;-;

Don't worry.
There's avatars that you can use to draw words or use a text to speech.

And yesterday I did saw a character that has a keyboard that writes words above it's head.

Hey, you can add me if u want, i am also a mute in VRC. ;) VRC Name "Kriekon"

Just don't think too much about it, if anything just walk around and when your comfortable enough try to talk to someone. Wish you the best on vr chat, there are lots of cool people on there : )
