I am teaching very basic computer classes to digital illiteraces, mainly Latinos that don't know what a window in Microsoft window is, I've been doing this two times a week bc I decided to push myself beyond my limits, and it's a very good place to practice my own fluency stuff, bc I like the trial and error thing. I think you should be in a group of people where they don't laugh at you, but I think eventually you should increase the pressure being in this kind of group, bc eventually you'll have enough experience to control yourself in this kind of stressful situations. PS: Not a native, sorry for any typo you could find.
